I know you can like items and I shared that link but my mate says the address shows as blank when hes checking out. Not sure if that is privacy issues or not any help would be appreciated never did it before
There’s not a wishlist option anymore. You can share your ‘saved items’ which is essentially the new wishlist, but it sounds like that’s what you’ve done already 
There isn’t an option to get something sent directly to you, they would have to know your address and manually type it in for the delivery address.
