Advance Auto has an on-line promotion that ends today, if you want to take advantage of it. Buy < $100 of stuff on-line (which you can still pick up IN-store, if you like), and save 15% - AND - get a $50 off coupon for your NEXT purchase, which will arrive by e-mail after Jan.1.

I bought a new battery for the R/C yesterday and saved $16 with this promotion. They also carry replacement pistons for the rear liftgate, @ $28 and change each. So a pair would be around $57 and change, but after my coupon arrives, they'll be $7 and change after the first of the year!
