mysupermarket compares prices from eight leading stores and lists them cheapest to most expensive. but shipping toilet paper and paper towels right to my front door can that really make sense? in fact a lot of the items i need, not all, but a good select selection of brand names. 20 minutes of my time to buy 12 items. now it s off to the local supermarket, the big box store, the problem here, crest, sensadyne, kirkland. they don t have my brand of toothpaste. so i have to get that someplace else. a few more stops for the items i am picky about. four stores, three hours, 31 miles of driving. clearly the online option is more convenient. but let s get down to the benjamins. the 12 items purchased from my local stores comes in at $141.62 including tax. but not including the value of my time or gas.
