You guys are right on indoor tanning lotions sold @ salons. Luckily, my salon doesn't charge too much out of the ass, for lotions, but a lot of people complain that you should only buy from a salon, it's the only legit source to buy tanning products. I'm sorry, but if I'm going to find it cheaper online, that's how I'm going to get it. I've bought many lotions from reputable eBay dealers and tanning sites and NEVER had an issue.
Hair products on the other hand, I've noticed that the prices for brands like Redken, Matrix, Biolage, Tigi, etc., are usually the same at stores like CVS and Target. Sometimes it's just easier for me to go into CVS at 9pm at night to get some Biolage mousse instead of waiting for my salon to open during the week. I've never had an issue with hair products that I bought somewhere other than a salon. IMO, they're still the same.
