Im 100% sure they are NOT allowed to put $0 on the package. Even if it is a gift, it has value which had to be reported to the customs.
Im also pretty sure the $115 (if I remember correctly) is the retail price, not the cost of making it. They might write it with the cost of making, which will be much less than the full price (a hoodie might be sold in shops for $50 but only costs the shop $20). Also according to EU law you shouldnt need to pay anything but VAT which depends on where you live if the package is under EUR150.
Pretty sure Epic wont “pay it for us” with an EU warehouse, but who knows would be a nice suprise.
Disclaimer: Im not an expert just getting a lot of packages from all over the world and by experience I know a few things. All my knowledge might not be true in your county.
