Isn't it funny how people will walk right over those pennies. But as gdjoslin has shown they can add up! Growing up in Michigan bottle deposit was 2 cents. My brother and I picked up bottles one year and was able to buy my Mother a $7.99 Vegamatic for Christmas. We were so proud.
My sister and I used to pick up bottles too! I think it was 5 cents for each back in those days. That is so funny to me that you did that too.
Heck, I still clip the coupons. I have had free Mt. Olive products for 5 years now. Just wait till they have the BOGO and then double the coupon. Then it's not only free, they give you a credit of so many cents.
