Substantial, even for a BITOG reader. 3 ecoboxes of PUP and PP found on Ebay for $110 (PUP) and $90 (PP) with free shipping + 40qts. of various 0w-20, 0w-30, and 5w-30 synthetics bought at $2/qt. during last year's AAP/AZ fire sales. 5-10 filters for each of my 4 vehicles, ranging from Fram Ultras ($4/ea. on Ebay) to OEM Toyota cartridges (<$3.50/ea. on Ebay) to some "Tearolators" for my '95 Dakota, clearance-priced from my local Meijer store during the rebadging for $0.89/ea. I'll use up this stuff---we keep vehicles a long time.
