How much do Target bags cost?

Excuse me, could you please clarify for me the pricing structure of Target bags? I'm interested in knowing if there's a standard cost for them, or if the prices vary depending on factors such as size, material, or any promotions that may be running at the moment. Additionally, are there any membership benefits or discounts that customers can take advantage of when purchasing these bags? It would be greatly appreciated if you could provide me with a comprehensive answer to this question.
