Sometimes, if you contact companies they will send you coupons in the mail!
Here are my rules that I live by:
1. I will never contact a company of a product I do not use.
2. I don't lie when writing to them.
3. I never ask for coupons. I tell them how good their product is and ways it has helped me.
Below you will find some of the companies I have contacted and received responses from! (This list will be updated as I get more responses)
