What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates. If you are looking for wholesale prices please feel free to contact us.

    Pros: Small and clear display showing all needed units (U, I, P and C). Cons: Capacity reading has a bug; every time when the reading rises from 99 to 100 the actual value shown is 99 => 1100, 1199 => 2200, 2299 => 3300, etc.
