This is a horrible, frustrating, piece of crap. I understand tech and I almost never give bad reviews. Stay away from this solution and do not buy any premium add-ons like GoldCart.
I did a completely new WordPress install, with a fresh database, fresh install of the cart and no interfering plugins -
Images don't work.
Downloads are busted - customer will not be able to download product.
Image gallery doesn't work.
Suddenly, the store will point to the wrong page and give 404 errors.
Terrible customer support.
This is all hype - bottom line - a bad piece of software. I just spent $50 for wp_estore. I recommend it highly - simple, and with a bit of ingenuity and tips easily found on THEIR site, I was able to finally mix products, services, and goods, shipping and no shipping, taxes and no taxes. Finally!
Do not waste your time on this. Look on the Web for 100s, maybe 1,000s of complaints!
