Best Price in Bulk!

Because we are a major distributor for some products, we price very aggressively by sacrificing profit margin whenever we sell in bulk. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores. Unlike those wholesale to public membership clubs, we do not charge any membership fee. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Essentially, you are paying 10 times on shipping. We don't think that is fair to you. Why? Most of the time, shipping a 10 lb parcel does not cost 10 times of a 1 lb parcel.

Here is an example:

Opentip	Others
Product Price: $8	Product Price: $20
Shipping for quantity 1: $12	Shipping: FREE
Quantity: 10	Quantity: 10
Total Shipping for quantity 10: $18	Total Shipping: FREE
Subtotal: $98 Saving: $102 (51%)	Subtotal: $200

Don't be shy. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Most of the time, we will match or beat their price, and give you a credit. If we lose to a competitor, it is our shame. We then know we need to work harder in sourcing to create values for you.

* Price comparison must be based on comparable brands or models and in bulk quantity purchase.
