I used to take packages to bell services, but as of my 2 trips in 2017, they could no longer ship them. It would be wonderful if that’s changed again. However, I could take merch to the gift shop to be mailed home. They can only ship items that you bought at DLR. So, you can’t ship back freebies (like the giant cup they give you at WOC dessert party) or your dirty laundry. You have to show receipts for the purchases, so it really pays to get everything organized before you go in there. The cost depends on how much your shipping, but the rates were reasonable. My memory is hazy on this, but I feel like the items they would ship had to be purchased from a Disney owned store. Like maybe we couldn’t ship back legos purchased at the lego store??? I really might be wrong on that point though.
