Dollar General

I purchased several items at the dollar general store #14405-geneva ny.
I am disappointed after returning home and reviewing my receipt.
Several items priced differently compared to price on shelve.
I try to stay within budget on my products and usually shop with lower prices
I however and very upset after realizing the price I paid for several items.
I truly believe the items on the shelves were very clustered yet I look for pricing on the shelves. Some items were very hard to find I price.
I could obviously take the products back to store but not knowing if they could be refunded is my concern.
