I can't say that I've ever ordered from this seller. I use Ebay a lot to find good deals on my growing equipment. I find it easiest to compare and price match everything. Sorry I can't help you with growlightsupply.com. But here's one of my favorite sellers on Ebay. http://stores.ebay.com/The-Hydroponic-Source. May I ask what it is you're looking to purchase??o_O
