FYI......these are the same sellers as Ali Express.
AliExpress.com - Online Shopping for Electronics, Fashion, Home & Garden, Toys & Sports, Automobiles from China.
I use Ali Express all the time for dog clothes. It is also really good for costume jewellery, mens/boys T-shirts, and household items that are a rip off here. A good example is the nail polish rack I bought my daughter. It was around $50 here but I paid $10 on Ali Express. It's just a giant piece of plastic and I think $50 is a rip off for that. I also bought a pair of earrings for $1 on that site. They came in Claire's packaging and I saw that exact same pair AT Claire's for $10!!!
I also bought Dorothy's life jacket on Ali. The EXACT same one was $47 at Pet Valu and I bought it for $7 on Ali.
Anyway, all the stuff comes from China (as does the stuff from that ebay seller). I have found that the quality is okay for most things.
The stuff takes a while to get to you (30ish days) but you can't beat the price.
