Dollar General

I received my weekly flyer in the mail advertising Dollar General had $2 Bath Towels. I received the flyer on Wednesday and been looking forward to Sunday to purchase this item. When arriving at the store to purchase, the cashier did not know about the item, she looked at the flyer and then proceeded to find the Bath Towels. She did not see them on the shelf, so she looked in the back. She said the store must not have received them. I tried a different store and the same thing, I called another Dollar General in the area, also the same thing. The towels were not delivered to any of the stores in my area, yet they are advertising them. I asked for a rain check on the items and the manager at one of the stores said Dollar General does not do rain checks. I am very disappointed because I was looking forward to making this purchase.
