We charge a small cart fee of $1.99 on all orders that are less than $10-15 depending on the market you are in. Sometimes we don't know exactly what the items you've ordered are going to cost at the store, so we may quote you a small cart fee but not charge it (yay!) or we may not quote it but end up charging it (boo!).
We know the fee can be a bit of a bummer, but it allows us to make sure that you can always get whatever you want from wherever you want.
