Payments are not showing in the shopping cart correctly. This is probably due to a glitch from either Paypal or due to the fact that we are engaged in the updating of the site.

We are sorry for any and all inconvenience this has caused. We expect to have the problem corrected sometime on Wednesday. Look for an update when it has been fixed.
