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.

Involvement Level: Expert (understands the inner workings)
Pros: Works out of the box with 5V microcontroller boards like the Arduino Uno. Just hook it up to Ground, 5V and a pin of your choice. Use writeDigital(HIGH) or LOW to switch the relay on or off (or rather close the circuit Common - Normally Open).
Cons: The screw terminals (NO, NC, C) are not properly labeled so you will have to figure out which one is which by yourself. The Common terminal is in the middle :) The click is pretty loud and may be a bit annoying if you put your completed project in the bedroom.
Other: Good value for money if you only need a single relay. Works great with 5V boards like Arduino Uno.
