Shipping is expensive, and it gets more expensive almost every year. We are not going to pretend otherwise. What we can tell you is that we work hard to find the most reliable and affordable way to get your order to you, and we pass along free shipping wherever it makes sense.
Free shipping on any order with two or more items. The one exception is bulk items, meaning the large or heavy products that have to move by freight or oversized parcel. If your cart qualifies, free shipping is applied automatically at checkout.
Most stores set free shipping at a dollar threshold. That works when you sell light things like clothing. We don't. We ship soil, amendments, and heavy real goods that are expensive and awkward to move, so a dollar minimum doesn't reflect what shipping actually costs us.
We are a small business with no outside financial backing, and we are not Amazon. We manufacture, pack, and ship everything in house so we can control quality, which means real people picking, boxing, taping, and labeling every order, and that means real jobs. When we ship a single item for free, the only way to cover it is to raise prices across the board, and we would rather not do that. Asking for two or more items on free orders lets us keep prices lower for everyone and keep shipping sustainable. We hate high shipping costs as much as you do, and this is the fairest way we have found to keep them down.
Every product page shows an estimated delivery window based on current fulfillment and carrier schedules, so you know what to expect before you buy.

We ship with FedEx, UPS, and USPS, and we pick the carrier that gets your order to you reliably at the best cost. We cannot guarantee a specific carrier unless you arrange it with us ahead of time.
Orders to PO Boxes often cost more and usually do not qualify for free shipping. Use a physical address to avoid delays and added fees.
We ship to Alaska, Hawaii, Puerto Rico, Guam, the Northern Mariana Islands, and the US Virgin Islands. Free shipping generally does not apply to large or bulky items going to these destinations, though Hawaii and Alaska have more flexibility depending on carrier policy. Rates are quoted at checkout or on request.
We ship select items to Canada. Canadian customers need to choose "UPS Standard Shipping to Canada" at checkout so your order clears customs cleanly and you avoid surprise brokerage fees. Orders placed with other methods can be delayed or rejected at the border.
Some products ship directly from our vendor partners and show their own estimated ship dates on the product page. Questions about these go to support@buildasoil.com.
Freight orders arrive on pallets by box truck or semi. We assume you need liftgate service unless you tell us otherwise.
Inspect every freight shipment before you sign. Count the packages and check for damage. Signing the delivery receipt confirms the order arrived complete and undamaged, so note any problem on the receipt before you sign it.
Full truckload (FTL) orders are custom quoted after checkout based on your location, order volume, and how the truck will be unloaded.
We email tracking as soon as your order ships. If it does not arrive, check buildasoil.aftership.com with your order details, or email support@buildasoil.com.
This optional add-on at checkout covers your shipment against loss, theft, and damage, and we fast-track those claims for replacement or resolution. Even with protection, photos and documentation help us move carrier claims along faster.
Send all claims to support@buildasoil.com. We do not process claims by phone.
Include:
Hold onto the packaging and any damaged items until the claim is resolved, since carriers may require an inspection.
We help with every carrier claim we can. But once an order is in the carrier's hands, we cannot control delays, damage, or misdelivery, and the carrier makes the final call on claims.
#1 BuildASoil Worm Castings - 2 Gallon is backordered and will ship as soon as it is back in stock.
Fresh, consistent, and from one supplier with quality control we have relied on for years. We test them at Logan Labs so we know the chemistry integrates cleanly into a soil mix: high in calcium, low in chlorides and bicarbonates, plenty of nutrients without upsetting your balance. The biology is part of all good worm castings. The consistency is the hard part, and that is what we deliver.
Castings are one of the most inconsistent inputs on the market. Two bags from the same brand can perform nothing alike, and the chemistry you cannot see is what quietly throws off a soil mix you worked hard to dial in. Here is what you are up against.
When every bag is different, you cannot build a repeatable recipe on top of it.
High chlorides and bicarbonates can push your soil out of balance before you notice.
Most brands never publish numbers, so you are trusting a label with nothing behind it.
We grow too, so we hold our castings to the standard we want in our own pots. We know the chemistry because we run it at Logan Labs, and we know the quality because it comes from one supplier we trust batch after batch.
We check the chemistry that matters for mixing into soil, so you know exactly how these behave in a recipe.
Plenty of nutrients without the hidden salts that push a balanced soil mix off track.
From one supplier with quality control we rely on, so every bag performs like the last.
Clean, black, and moist. Mixes into soil or brews into tea without the mess.

Great stuff!! Now I come to understand that there is even something better for my new gardens and the wife's new flower gardens??
Well pleased with the quality of the worm castings. Should have been a 4.9 rating but that's not possible. My only problem was the price for 135 pounds of castings. But I did get a discount offer for my next purchase.
Good stuff!!
Best products hands down.
BAS worm castings!! Need I say more?!
