You are definitely not alone with this!
I dont have a lot of money... a pony a month and thats it... mostly. Some exceptions are made.
I really love the G4, I love the show, I love the ponies! But... all those exclusives, specials, bla... it kinda makes me insane. It totally stresses me, even the fact that the very most G4 MLP stuff is so insanely expesive for me, because not a single store in my area carries MLP and I have to buy online and pay heaps of postage all the time. Even the german online-shops dont have the G4 I want, so I need to pay the min. of $7+ postage for one lose brushable pony.
Yesterday I got Sunset Shimmer. She arrived fast, price was fine and everything else was alright, but I really freaked out, when I saw her eyes. Rarities head-mold but different eyes, just painted over the mold, not even close to fit!! And for THAT I spent my money?? Im so so so angry and disappointed :/ It made me think about the whole G4 thing again. Do I really want to be stressed by them? Do I want to spend the little money I can on those ponies and stuff?? Im close to turn my back on them :/
