Thanks MikeH. This is exactly the point I was trying to get across. Was working late last night and brain was a bit fried when I came across this.
So, as MikeH said, my client (and other clients I have used this package for) doesn't want their customers to be forced to set up a Paypal account when they purchase from their site as they (and I) feel that it may force potential buyers away as we do know people who buy online but are not interested in using Paypal.
After finally clarifying my point (thanks again to MikeH) how are my clients supposed to take payments into their Paypal account without using Paypal Express??
I was about to buy another 3 licences for Powerstore (already bought 2) for this and future clients but am now having to consider going elsewhere if I cannot provide the client with the payment options they require.
