Cost of Vinyls?

[omably]

Hello Everyone at AHS!

How are we all? I've been searching on eBay all night and I've seen some Ayumi Hamasaki Vinyl's... I'm not exactly sure what they're meant to look like or how much they are supposed to cost, they appear to look exactly like the singles and are described as being in excellent condition. They range from the prices of $18 USD to $30, not sure if they're fake or even if there is such a thing as a fake vinyl but yeah, I haven't really paid but attention to them until now but... yeah any help would be much appreciated!
