Hello,
Since IPS is known all over the world, I thought it would be a good suggestion to allow customers or new customers to be able to choose there own currency, like if you gave an option for the site visitor to choose a currency, you could have the most popular, GBP, USD and EUROs, I think this would make it easier for visitors to determine how much the product will cost them in there own currency, I myself would benefit from this as I live in the UK so I use GBP and find it confusing sometimes converting USD to GBP.
