[Guest Checkout] Discount not applied in Guest Checkout

I've noticed when there's a discount being applied to a product, it disappears when the visitor signs in using the Guest Checkout module. You can see this on my client's shopping cart (http://www.survivalstrategies.com/store) by adding either Clinic Software product and then sign in using the Guest Checkout. You'll see the discounted price of $95 goes back to $195.

The discount can only be applied to Customer Group "Default" or "Wholesale" in the admin product section. Is there a way to add Guest Checkout visitors to the "Default" group?

Anyone have any suggestions?

Shoulda went with my Guest Checkout system It works fine there

I am using yours. I just customized the layout of that first Guest Checkout page because during user testing, it was apparent that the options (guest, sign in or create) weren't understood that easily.

guest checkout works with coupons on my version!

You must have an old version of mine The later versions use the default customer group id

Qphoria, I had 132.4. Upgraded to 132.6 and that seems to have done the trick, thanks!

Daniel, I see that it is in version 1.3.4. That's great. When I have more time, I'll have to upgrade the shopping cart to take advantage of all you've done. Thanks for the hard work.
