I went to SDM tonight to buy some new nail polish. I grabbed 2 Essie nail polishes, since they were on 2 for $16 (or 1 for $10.99). When she rang them in, they came up as $10.99 each. I asked for a price check and sure enough I was right - so I ended up doing a SCOP on one, and getting the other for $8. Woohoo!
