goto edit product: Under short and detailed description enter "Member Price $235" (or whatever you wish). This should be on a separate line at the bottom of the description area so it's near the full price.

The discount for membership then is in reality an X% off coupon. ie: membership gives a person 10% off, so you give them a 10% off coupon, and the "Membership Price" is 10% less.

Then use coupon function for members. Members get a "membership" number or code instead of a "coupon." Edit coupon labels as required to indicate membership rather than coupons. You'll need to send them their unique code in an email (I'm fairly certain this can be automated, but I don't know how).

If you want to reward certain customers some more, you give them a "Coupon Code" for the next order. Tell them to place that code in the "comments" box on the order form.

I know not if this is the best way, but I wrestled with this problem for some time and decided on this method so that the basic X-Cart would remain pretty much intact.
