Vendio is just a hosting for e-carts. , yet provide no way of tracking the reputation for "seller". and Vendio have zero support if you lose money on this.
Be aware. there are many scams "sellers". look for signs:
cheaper then anywhere.
manual payment methods. (usually they want you to wire the money.)
Ordered a school Text book from one of the sites for less then $20 dollars. I was suspicious after I looked around the site a little and was ready to write it off as a lesson learned about buying cheap text books from unknown retailers. To my surprise it actually showed up in the mail today. The cover is different from the regular text book but this fact was disclosed in the product description. However I tried to link to the store so that a fellow classmate could purchase from here as well but the link seems to have broken.
I haven't purchased anything yet but friends have, and they say http://www.vendio.com/stores/gracefullymodest/ is good.
Seems safe too, I don't pick up any tracking services on before said page.
This is a overpriced multi selling channel manager that adds some unneededconfusion to the mix.. goto inkfrog or some other 3rd party and save yourself the time.
