I'm trying to decide where to buy a MFLB, because I am confused. One is for sale at puffitup.com with a coupon for 15% off, but I've never dealt with the company and am scared that it might be a scam. a magic flight launch box for only 84 dollars with a grinder? I love the sound of it but it sounds fishy. Or should I buy from the website that the company itself (magic flight) has on its website? (there it is 100 with no grinder) What to do?
