Buyers should be aware that many of the bonus codes, and codes offered digitally, are the same for multiple sellers.  The bonus codes work on multiple MyCokeReward accounts, but only once.  When you buy another set of bonus codes, you are likely to get the same ones again.  I found this out the hard way, and, while I only paid $2.50 for the lesson, I was disappointed by it.  Plus, with the whole retaliatory feedback stuff, I ended up giving the sellers positive feedback, another lesson I learned the hard way.  My suggestion is, if the item description says they are bonus codes, don't buy more than one.

In fact, don't by them at all.  Pick them up free here:
