Re: Current discount codes at SSC: 2016MAR for $20 off
This is how it works (for me anyway)... put an older PF in your cart. Let it sit. Before your session times out navigate away from the cart page to keep your log in active. Don't be quick to click though, I think the site senses the awakening of other links, which will activate the pop up.
Sometimes the item oddly disappears from your cart, just re enter it and start over.
The code will be applied to the cart order, just cut n paste into your wallet if you wanna apply to something else or just hold on to it.
