Ummm, Possibly But taking into account that the catalogue is £ 4.25, being posted for free but postage would still cost £1.53 ( 2nd Class , may be a bit less if they use franked mail. So £ 2.72 after postage, less printing and packaging costs and card charges I can not see that they would make that much anyway really.
Ok not as easy as sharing on line but I would think that most who buy the catalogue would also share it
Yes is online but having a PDF is more useful at times.
Oh well just have to wait until the next batch.
