I'm reaching out to get more detailed information about your wholesale pricing and the different tiers you offer. As I'm considering a substantial order, understanding the pricing structure is crucial for me to make an informed decision. Could you please break down the cost per unit based on varying order quantities? Additionally, if there are any discounts or incentives for larger purchases, I would appreciate if you could outline those as well. It would be great to know the minimum order quantities for each tier and any potential shipping costs that may apply. This info will really help me in planning my order effectively. Thanks!
