The promotional code is TY10POFF. I already have 200 of their 16x DVD-R TYG03. (Linkyo) They’ve been the fastest/ most efficient media for my 20x Lite-on burner, so far. I don’t know how they work on other brand burners. I just ordered another 100. The Linkyos get shipped in Four squared shaped, 25 pack cake boxes. Which are allot better than the round shaped twist cake box IMO. Also free shipping.
