Hey, I'm looking at purchasing the idevaffiliate system for my website on shopify (is it easy to integrate?) and just wanted to get some feedback. Is anyone here using it? Has anyone used it? Do you like it? I tried calling the sales # and nobody ever answers or calls back. The system looks pretty slick, but before I fork out the cash I figured I'd ask around here. Not interested in wasting my time or my $$$. Thanks!
