I just received an order of Purell Wipes - individually-wrapped sanitizers, from Restockit.com for $5.79 per box of 100. Total for 3 boxes plus shipping was $ 24.32 . That comes out to 8.12 cents per wipe (they're 5" x 7"). Undoubtedly there are other brands that one can bulk order, but this seemed pretty good. Cheaper than buying at Wal-Mart, anyway. Mango
