No option for royal mail 87p postage

[footballcardsuk67]

Private seller here. Always used to be able to select  2nd class letter postage. Now it only lets me have large letter for £1.55

My items don't need to be in large letter 

Please help, it has slowed my sales down with the increased price of postage

There's a problem with letter post with Simple Delivery at the moment.   eBay know about it and are trying to fix it.
