Amazon currently has Luvs Ultra Clean Wipes 8x Tub with Refills, 576-Count priced at only $12.79 when you shop with Amazon Moms. This comes out to only $0.02/wipe which is right around my target "buy" price. Amazon prices change often and without warning, so I can't guarantee how long this price will be available. And remember, if you have any Amazon gift certificates from Swagbucks you could get these for totally free!
The Luvs Diapers with Ultra Leakguards Big Pack is also on sale again for $30.39 with the Subscribe and Save option, making them as low as $0.10/diaper!
If you order these, don't forget to cancel your Subscribe and Save order once your wipes/diapers arrive, unless of course you want to continue to periodically receive them. Just because you order with the Subscribe and Save option does not mean that you need to keep getting these items. You can cancel your subscription at any time.
