Welcome to the arena! I can't help with the ponies in the first photo but in the second photo starting at the top right they are:

Third photo is:
Tootsie, Shoreline, Applejack, Fifi, Skydancer, Sparkler, Windy, Princess Tiffany, Parasol, Glittering Gem, Firefly, Parasol, Fif, Tic Tac Toe, and Seabreeze.

5th pic is Baby Moondancer, Baby Surprise, Speckles, Puddles, Christmas Baby Pony, Dangles, Jangles, Squirmy, Spunky, Kingsley, Surf Rider, Zig Zag, Pockets, and a Fairy Tail Bird.

6th pic the large white pony is a soft and sleepy newborn named Hushabye and they can be worth quite a bit. The smaller playset is the Poof and Puff Perfume Palace and the large one is the Paradise Estate which is the largest playset ever made for ponies and thus pretty pricy.

Hope that was helpful! You've got some good stuff! Hopefully someone can give you some accurate values for them!

Thanks for the replies everyone. She messaged me late last night and said she's "been advised to open a dispute" but I haven't gotten any notification of a case being filed yet. I've got all our messages saved if she does open a case. Hopefully everything turns out ok! Lygeia it's so cool to see another pyrex addict around!

Recently I started selling on eBay again and I've encountered my first problem as a seller.

 In addition to ponies I also collect vintage pink pyrex. I picked up a bowl in orange on a whim at a thrift store because it seemed to sell well. I listed the bowl for $40 based on completed auctions but never made any assumptions as to what set it belonged to. A buyer messaged me and we got to chatting. She believed the bowl was a set completer for her but I assured her I didn't know what set it belonged to as I don't collect that color. Eventually she made an offer that was a lot lower than my asking price, $15 to be exact. I accepted it because she seemed nice and it was still a decent profit for me. When the bowl arrived she messaged me because it isn't the bowl she thought it was and thus doesn't complete her set. Now she's asking for a refund and I'm not sure what to do. I understand her frustration, but at the same time she made an assumption and it turned out to be wrong.

Tl;dr: is it fair to ask for a refund when your assumption about a purchase turns out to be wrong?

I bought a MPP with her box and most of her accessories last year. The ribbons were in super rough shape but I'm almost positive there was a red one, about twice the thickness of a regualr g1 ribbon. I can't be sure on the others though, and I'm not a home right now. I'm sure someone will have them though. I agree that the yellow one is probably a faded peach one.

I wish I had the confidence that most of you seem to have about pony shopping! If cashiers ever say anything I always say "oh yeah, it's my niece's birthday this weekend! I hope she doesn't already have these!" and I always make sure to get a gift receipt even if they don't say anything. Seriously my imaginary niece has a great life! It's her birthday almost every weekend and she always gets all the new pony stuff haha!

Luckily I don't think I've ever gotten a bad response when talking about my collection! It's usually a lot of shocked expressions and ooooohs and ahhhhs when people see it in person. When I had a pony room my extended family always wanted to see what was new and how much it had grown since the last time. My favorite was when little kids would see it! I had a much younger cousin and some girls I babysat for see it a few times and they were just in awe! As others have said, I'm not too shy with my collection and if someone has a problem with it or is a downer about it then maybe it's time to reexamine the relationship.

As others have said the Billy bookcases from Ikea are the nicest in my opinion. I think they even have corner ones to maximize your display space. I've always wanted a pony spa area too! Maybe something like a camping sink that's self contained and doesn't use a lot of water? It could prevent any flooding problems. You'll definitely want something with drawers too! I like to use the ones with the fabric drawers they have at target but depending on how much you need to store you may need an actual dresser. If you're OCD with checklists and labels like I am you'll probably want a desk or a table too. Congratulations and good luck!!! I can't wait to see it all finished!
