My advice to anyone considering eBay is to just hold off for a week or so. Allow the market to stabilize. I know a lot of people (including myself) has that "I gotta have it now!!!" attitude, but if you wait, the prices will swing in your favor. On the first day Mulan was released, they were going for $250-$300 on eBay. Today, just a week later, they can be had for $150. Yes, it's still an $80 markup after tax, but it's half what the highest prices were just 7 days ago.
Will that hold true for Snow White? Tough to tell, but I'd lean towards yes and here's why: like most things, the flippers will end up getting greedy and ruining this for themselves.
Know why Ariel is still selling for upwards of $350? Because Ariel was released before the flippers knew this was going to be a hot collection. There are only 47 up for sale and 3 weeks after it went on sale, there are just as many that have sold as there are Snow Whites in ONE DAY.
There are 600 Snow Whites either currently for sale or sold and this is just the first day. The number of auction that will go up in the coming days will continue to rise as people receive shipping confirmations and know they're getting the doll. Nearly 900 Mulan dolls have sold or are up for sale right now!
Supply and demand. Just stay patient and watch the flippers price themselves down. There are only so many people willing to jump and pay $250 before the market settles and they see the average person is only willing to pay X amount over actual cost.
I think the same will hold true for the remaining dolls, but I don't Ariel will see a drop in price anytime soon, and maybe not Belle either.
And if you're a person who refuses to pay a penny over $60+tax, then I'm sorry, but you're prolly out of luck outside of the random nice person on here or Facebook
