First off: once you're at the item's page, there's no option to "buy now" or "add to cart". Instead, there's a "click to find" button. Huh? Helooo, I'm already at the product page. What am I supposed to find now? When you click on the "find" button, you get a looooong page with a zillion items, and your item is buried in the page somewhere, not at the top. This scheme of things was extremely counter-intuitive for me. Playing hide-n-seek with the buyer!
Now on the long page with your item, there are several links for your item; item name, a "buy" button, etc. Many will take you back to step one. Deja Vu all over again! One will take you to another page where you can add the item to your cart. Try changing the quantity. This is where I had to clear cookies multiple times and retry.
For my item, the item rebate page said there was a limit of two. When adding to my cart, it said the limit was one. But it let me change the quantity to two. Then wouldn't let me change it back to one. Go figure.
In one link on the main page (customer service or whatever, can't remember), they said tax would be charged only for some Canadian provinces. I'm in California. Then in the main page for the site, they said shipping would be free if the order was over $25. Mine was around $29. On the final checkout page, they charged me tax, and $4 S&H, wich together was nearly 20% of my order total. There was no mention anywhere (easily found) that there would be a S&H charge.
That's when I gave up.
Way, way FUBAR.
