Can't find edit coupon page/area

[jpreskitt]

I feel this is a really stupid question, but I cannot find where users enter their coupon codes in the front end. I'm running VM 2.0.2 on Joomla 2.5.
Any help is appreciated.

The coupon entrybox does not display unless you have selected "Enable Coupon Usage" in Configuration/Shopfront.
