At Advance Auto Parts, buy one select item and get a second one for free. (Add two to your cart; discount shows in-cart.) That's the first BOGO discount we've seen from Advance Auto Parts since July. Choose in-store pickup to avoid the $9.99 shipping fee.
A best bet is to buy two quarts of Valvoline SynPower Full Synthetic Motor Oil for $8.99 with pickup at Advance Auto Parts. That's the lowest total price we could find by $21.
June brings some big deals and sales, but you're better off postponing certain purchases.
