I didn't get any letter at all. Mind you I did get a letter saying welcome to Slimming World in late March when I joined in January! I dunno why it's so late?
I got my sticker on the 15th March for my Club 10, I even had to point out I got it. I have lost more since then so I should have technically got it in the last week of May (either 24th or 31st). I have texted my consultant anyways about it.
Reason I'm being anal about it, is cos I need to save money, and that €9 fee would mean a lot to me!
