Actually, TY CDs are hard to find at the retail level. Many of us don't have a lot of K-Marts in our area, and the ones we do have were cleaned out by greedy bastards months ago. Even worse, because of the nature of the K-Mart sales, it's hard to price match to places like Best Buy (they only match straight price reductions and not 2-for-1 sales or percent off sales, etc.), which still has a few spindles of TY CD-Rs laying around, but not enough to meet the needs of more than a couple of people.
The only way to get TYs or MIJs in most cases these days is to buy Maxell or Sony music CDs, or Maxell Pro CDs. Unfortunately, all of these are way overpriced and rarely go on sale.
So, no, it ain't that darn easy.
