My first DVD I bought from Advancedworkouts.com after watching Cathe on FitTV. Pyramid Upper & Lower. I was sooo hooked. The owner of Advanced Workouts guarantees all dvd's for life, and even buys back ones you don't like in 30 days for full price.
The second Cathe dvd I bought was on Ebay from briantiffhailey (Power Hour+)who was fairly new (under 100 transactions) with a perfect rating until I realized half the DVD didn't work. I complained and got all sorts of excuses that he was vacation and then threatened to leave bad rep plus get in touch with Ebay. He refunded my money, then I find that he is no longer a registered user, but another person is now selling from the same place in Washington. Personally, I don't think its worth it. Jen gives me discounts for multiple purchases and free shipping and it comes out to only a couple dollars more for a new DVD. But I know its legit and working with an honest person, who really gives great customer service. She's even got a sale going on all Cathe dvds plus shipping is free with a $20 purchase.
