Postage fee for UK

Some of you maybe aware that Royal Mail are once again increasing the postage costs this will be the 3rd time in 10months so I have decided to dispatch via 2nd Class, I have a set 1st class fee £3.70 not including packaging, so in reflection I shall be charging £3.50 for 2 nd class UK postage this is including my packaging costs. I will still be giving free postage to orders but that will also be increased to £35+ for UK customers. International tracking will also see a slight increase to postal fees.
