Try funky pumpers it's a site I've actually discovered myself today
If u want a case for your equipment try eBay or diabet-ezy or the best on is desang
I too have the 640g and the best place for stickers for all pumps, meters and CGM is by far https://pumppeelz.com/ and you can even design your own. Also for good screen protectors and quality silicone pump covers medtronic sell them at their webstore, they make excellent pink purple and blue ones here for the UK https://shop.medtronic-diabetes.co....ategory:Accessories&pn_ps=all&content=product each country has their own medtronic store with similar prroducts, plus medtronic don't charge a delivery fee.
Brilliant news - i'm on the 640g too I got my first belt from Ebay 2 years ago and I still use it now - lots to choose from so it's down to your personal choice.
