When I looked at your site...
When I looked at your site three days ago, this Bibler/BD tent was 20% off. Have I missed the opportunity? Did I mis read the ad?
I wonder if it will go on sale again ...
Backcountry.com has several semi-annual sales, holiday sales, and "we just want to hook you up" sales throughout the year. With that said, these sales can come and go within a day's notice so stay tuned to the Backcountry.com notices and be ready to grab that item when it goes on sale. You can also call or LiveChat with a customer service gearhead who may be able to help explain the process further.
At the time of this answer, the tent is on sale for 20% off!
