I walked down to Wal-mart today on my lunch break with my friend from work. I returned a pair of jeans I bought a couple of weeks ago, which counts as interacting with the Wal-mart Experience Engine. The return was quick and easy, despite not having a receipt. There was initially a bit of a line, but someone noticed a line was stacking up and came up to the Customer Service Desk and broke the line down quickly. They put the return money on a wal-mart gift card (perfectly acceptable since I didn't have my receipt) and I was on my way.
