I returned Memorex DVD-R and DVD+R and received a full refund plus the return shipping cost. Both spindles had been opened, and two disk were removed from the spindle of 100 DVD-R. I only buy from Meritline.com now and only buy Ritek G04. My experiences with this online merchant have been fantastic: No Returns, and Ritek G04 burn perfectly in my Plextor 708A (no coasters!). Furthermore, Meritline.com carries all the brands of recordable DVD media at the lowest prices on a regular basis with the exception of extreme discounting by other merchants. I guess I have become a loyal customer of Meritline because I don't bother to shop any place else now. Their media is priced right, and always seems to work in my drives: Plextor 708A & Samsung 352B. Also, their media plays perfectly in all my stand-alone DVD players: That is why I only buy Ritek G04 and only buy from Meritline!
