印度采购需求：UTECH皮肤分析仪，专业皮肤分析仪，皮肤分析仪设备，3D皮肤分析仪

I'm interested in understanding how you set up your wholesale pricing tiers for your products. Could you provide some insight into the factors that influence your pricing structure? Additionally, it would be helpful to know if there are any minimum order quantities or volume discounts available at different pricing levels. This info will assist me in evaluating potential purchasing options. Thanks!
