Old Navy b-day sale and $10 off $50.

Old Navy is turning 15, it seems, and to celebrate, they're having a big ol' sale where many items are $15 and under. Plus, some coupon codes:

• $10 off $50 with code BG7R1CKRXHGL
• 15% off your purchase with code ONBDAY15

Looks like a lot of it is unloading summer clearance stuff, but who knows, maybe you do need some tank tops and polo shirts. In which case Old Navy has you covered.
