Here is a link to where I first read about the "5 A Day" project.
She has a wonderful blog and even has spreadsheets that you can download that include the websites for over 400 companies that you can email, and there is a place in the spreadsheets to note when you contacted them and to note what you received from them. It's good to keep track of this so you know when it's "safe" to contact the companies again ~ usually wait about 6 months between emails. You can also see pictures of all of the amazing coupons that she has received from various companies.
Since I am so far behind on this, I sent more than 5 emails today...here is a list of who I contacted:
Fresh Step Cat Litter
Glade (this was a complaint about a product that was damaged when I opened it)
King Arthur Flour
Nathan's Hot Dogs
State Fair Corndogs
I will let you know when I start receiving things from these companies, and in the meantime, check out the website above and download a spreadsheet...it makes it super easy.
Don't forget to let me know who you contact and whether they send you anything!
