Sparked Innovations review for Sami B2B Wholesale Pricing

A good concept but needs refining and debugging. I've had to write into support a bunch of times for things that should work but don't. People are waiting on me to implement a wholesale solution to our site and I've lost three days so far. Also, it takes a massive hit to your page load speeds. Just toggling this app on and off takes me from a B-C on GTMetrix to an E-F. Customer support is friendly, though it's a bit inconvenient not to have US support in a similar time zone.
