Confirmed: coupons not being applied/carried over when going from Checkout to Review Order page. On Checkout page it shows the discount but going forward, no. I am using 1.0-rc2 with uc_coupon_2.
I would be willing to help sponsor the finalization/fix of this EXCELLENT module (the improvements are great). We're a bootstrap startup, low on cash, and need it for prominent blog sites that want exclusive coupons for them to promote us. I'm willing to help if a few others can go in with me to defray the cost and get this sooner than later. Let me know, BlindWolf, or anyone else willing to get this going NOW (I can do this only if others can help). Send me private msg, or in comments(?). Thanks, team.
