Keep in mind security, otherwise let your member gift you as they please.
Camming historically has always had the option to give gifts; studios used to buy gifts for models on members behalf.
I would not recommend using your own address, I have recieved receipts from manufacturers/ distributers containing hidden addresses a few times in gifting.
Common sense would also be to wait for any gift to arrive before trading services of any kind for gifts.
Think of how you will reward/ thank your member. From the members end it can be a bit of a mixed experience.
For sending multiple items, keep in mind delivery costs, using the same 'store' and sending as one package saves money.
A gift is usually given in place of some spending by the member on their cam site/s. This can mean you recieve more, but only if it is something that you want/ need. Used selectively recieving gifts can get you some awesome rewards.
Recieving money directly/ gift cards is always a good option. Keep in mind cam site rules on gifting (Usually it is banned).
For my experiences of gifting, I've gifted these type of things to models: Money (direct transfers), plane ticket, cameras, tablet, shoes, dresses, winter clothing, lots of hair products and accessories, makeup, perfume, fresh flowers, books, personalised diary, home decorations, baby toys, sex toys, and jewellery. For many members it is just part of the experience of camming.
