Not sure how long this error has been happening but i noticed this the other day when a customer called me to point it out.

The RRP how can i get the "you save" price to display including VAT??

my store shows the following

Retail Price: £480.00
You save: £275.00 (69%)
Our Price: £150.00


the 275.00 shown is without VAT as the saving is £330 (275 + 20% vat)

how can I fix this?

I have askd this in the mod support post but with no reply.
