I use promotive often. Over 90 brands and always adding more. Some discounts are less than wholesale! Some brands take a little while to ship, so if you need something quick, you will have to order elsewhere. Still compare with with other sites. I have found eqiuvlent deals on Amazon and chainlove, but most of time, you can't beat it. HUGE potential savings !!
I've ordered products from Pearl I, Crank Bros, Nuun, Cliff, sport beans, Ergon, and more without any problem.
