royal mail increase

Just a reminder about the increase by royal mail  in the cost of posting will go up on the 2^nd of April but as it is a holiday weekend my shipping costs in my etsy shop for ready to ship items will go up on the 28^th as items bought on or after that will not be posted until the 2^nd as post office will be closed over the holidays. made to order items will go up on the 26th as they might not be ready to ship before the holidays.
