Could your pets able to purchase what they want if you give money to purchase at superbazaar?

could it possible to train your pets to make buy according to its wish.Could your pets able to purchase what they want if you give money to purchase at superbazaar?I don't think that an anmal could accept the concept of money. Many animals are extremely loyal to there human, pair, or pack. Due to this fact i think they would not be able to relize the concept of trading a peice of paper and then taking a wonderful product like a bone or mouse toy.
