The guy (owner?) over there can be a bit pushy - I ordered a light from them a month or two ago and he decided that he was going to try and talk me into purchasing an Icecap ballast (and endcaps, etc) instead of the sunlight supply lights I had intended to order (and in fact did order). Of course when I went to view my account it listed the Icecap ballast, etc. and not my sunlight supply fixtures. I called to have them refund it, but it took 4+ days for them to get the order correct. Similarly, the first refund they did was for the wrong amount. Also, he tried to tell me that the price they had for the sunlight supply fixtures online was incorrect, and tried to charge me an additional $15/fixture above what it was listed for on the website (oddly enough, the product # was also incorrect, so when I did order these they still displayed wrong on my account, so I had to call and call and call to get it fixed - they weren't answering their phones despite it being business hours). I happened to find them the next day for $15 cheaper, and inquired about price matching. I never heard back.
Every time I called this guy tried to pitch me a different product, including their substrate/fertilizer system. He wouldn't tell me much about the substrate when I asked, and said he "guaranteed" success only if I used it in conjunction with their root tabs. I HATE pushy salesman.
I may order from them in the future, but if i do I will definitely be prepared to stand my ground and not be talked into anything else by this guy.
In fairness, I do think you'll get your refund (i think they run a totally legit business, they're just aren't good at listening to customers in my opinion). If you're easily persuaded or talked into things, then I would try and avoid AP.com.
