Plans restricted to certain tax zones or price based on zone

I am setting up the membership plan for a UK based car club where we charge a surcharges for European and Worldwide members.

I have set up a promotion to add a surcharge for Europe which works OK, however the member is initially presented with the UK price and then after they click on the plan they then see the surcharge. I have added text to say surcharges will apply for non UK members but is there a way of showing the actual price when the plan is first suggested, or alternatively restricting plans to certain zones?

CBSubs Promotion can override the price display of plans. See the parameters under the Display tab. As you're doing geolocation based though it may not work as it uses the CBSubs invoice fields to determine location. So if the user doesn't have an invoice address saved yet (primarily registration) it may not work.
