Which London boots stores sell replacement tens pads?

[me23]

I have a boots TENS machine but need new pads, I have been into two local boots stores, clapham junc and wandsworth but they only sell the ordinary tens pads which aren't the correct size. Anyone know where I can get some? don't want to order online as I'm 37+2 so want them asap.
TIA

Don't know if it is any use to you but I think that the branch in Whetstone, North London has them. Have you asked your local branch to order some in for you?

Tbh if you order them online you are likely to get them quickly.

Thanks the earliest I can get them if I order is tuesday, so will have to risk it. I'll try phoning a few more stores around sw london tomorrow to see if they are in store.
