50 1st class stamps - self adhesive ?

I have several sheets of 50 self adhesive 1st class stamps. The price is 28.50 per 50 stamps which is a 5% discount on the price in the Post Office. The buyer can pick them up from me or I can post them out in a hard backed envelope for a small additional cost. Please get in touch if you would like 50 or indeed multiples of 50. Thanks.
