Adjusted pricing for issues and bundles

Hi y'all. Just a heads-up that we'd had to up the pricing of issues from a £ to £1.50 and bundles from £3 to £4. Paypal has taken a deeper cut than we expected, 35p out of the issue sales, leaving us after itchio's cut with just 55p revenue from each. The additional 50p per issue will cover the fees and leave us what we originally anticipated to put back into SCANLINES. The design quality of the 'zine and page count has been increasing, so we feel its worth a little extra, too. 

We've also belatedly added Stripe as a payment option now; if most buyers use that, we'll be able to drop the pricing back down a bit.
