Hi there,
Just posting in case others are searching for a cheapy too and might get stung - I've seen tons of low priced Ergo carriers in eBay sold by sellers who also also sell Benefit makeup. They only seem to sell these two brands, lots of negative/neutral feedback saying the makeup is fake, with the occasional one saying the Ergo was fake too.
I have to assume it's all the same seller under lots of different guises.
Anyway, check their other items before bidding on an Ergo carrier, and if it's Benefit makeup, avoid!
HTH!
