P&P charges explained:

P&P is not only the price you see on the stamp/label!
It comprises of the actual royal mail charge, packaging and because we are a VAT registered business, the VAT content @ 15%.
You will receive a eBay generated VAT invoice with your goods, where the P&P charges + the VAT clearly visible.
Our P&P charges are competitive with our competitors (who may be not VAT registered), you pay us what we pay the postman, for packaging and finally the lovely VAT people!
Please bear this in mind when marking our stars!!
