Costco already offers many deals on a variety of goods, but there's a way to possibly save even more if you're willing to be a bit sneaky about it all.

Pre-earnings options volume in Costco (COST) is normal with puts leading calls 10:9. Implied volatility suggests the market is anticipating a move near 3.2%, or $31.83, after results are released.
