Repeatable Target Freebie
There are lots of $1/1 Tide coupons out there. If you use them on these travel sink packets, you will get them for FREE. Plus there is another $1/1 coupon inside these packets, so you can just keep doing the deal over and over.
These packets are ideally for washing clothes in the sink while you are traveling, but you could easily use multiple packets to do a load in your washing machine at home.
