I know this is in the "Ask-a-model" section,
but would like to just add that email giftcards are by far the safest option (excluding tokens of course)
the thing you just need to be careful of is fake emails made to look like they are from amazon, giftrocket etc
Always check that email is in fact from amazon and to redeem it BEFORE giving the person anything or doing anything like a skype show for them. I've often heard of guys ordering a gift, model does skype show with them, then they just cancel gift after. IGNORE any email from the person like - "oh here's a pic of my amazon account as proof or here's a receipt," all fake.
Some models put a email address in there profile and mention to use it for email giftcards, but IMO this can be a bit risky because it gives any asshole the chance to email you a virus hoping you will open it, so if you do add it to your profile be very cautious of emails.
For a while some assholes were PMing models saying "Hey i just found a recording of you here's the link", and it was a link to a virus or some spam crap iirc, there's nothing stopping them from searching through models profiles and doing the same with emails.
You could just make a graphic on your profile saying something like "If you want to buy me a gift off my wishlist, mfc mail me what gift(s) you are interested in buying me" then when they do , then u can give them your email. Would maybe reduce the chance of anyone emailing you.
I agree with Teagan, also having a PO Box in another state is far more of an inconvenience than just asking for email giftcards.
Someone knowing your PO Box address, gives them a place where they know you will definitely be. I've heard plenty of models say on cam something like "i'll check my PO Box tomorrow before i cam" or "hope your gift is there tomorrow"
