I don't often even bother with wishlists. And, if I do, I only buy things I know she'll use. To date, I have bought 3 things off of 3 different wishlists, the most expensive being $30.
I'm considering buying a few things for one model I know, who just moved into her first new home. But they're things like bedsheets and such. Practical things, that aren't overly expensive.
It's funny, because I was talking to her after I bought her some bath products from her list, and was mentioning how some people, not even just models, have the most inane and super expensive shit on their wishlists. Like new $2k+ laptops... and her response was 'like anyone is going to by me a laptop.' And, to be fair, if I'm spending $2k+ on a new computer, you can be goddamn sure it is for ME and not someone else... I don't even spend that much on myself in a single purchase more than once every few years (normally to upgrade my computer to a newer model).
It's not even just cam models who have these outrageous things on their lists. One girl, who does a lot on Twitch (so not even what we would consider cam modeling in the sense as seen here), has some really expensive shit on her wishlist, and I just laugh. Laptops, super expensive designer dresses, the PS4 and Xbox One (that someone supposedly bought her, though it wasn't a day one edition, so that could still be cancelled before it ships in December)... and she actually expects people to buy these things for her. I find it funny as hell.
It's even gotten to the point of 'girls' on Twitter sending out wishlists to their followers or even random people with expensive products on there and expecting people to buy them for the 'girls'. I put that in quotes, because it's not always a sure thing they're even who they say they are.
The things people put on their wishlists can get pretty stupid. Hence why I don't even bother to have one for myself. If I want it, I'll save up and buy it.
