I absolutely love Ardell lashes. I think they're relatively new to the UK market (I've only recently started seeing them in Boots) but they're a firm favourite across the pond. My go-to lashes are the 131s which normally set me back a fiver in Boots. However yesterday I went to TK Maxx and they had loads of them for only £2.99! I picked up some 131s and 101s (which look massive & amazing). I've seen them in 3 different branches of TK Maxx so it seems like they are widely available there.
I also noticed that Superdrug have a 3 for 2 offer on their Eylure lashes so if you're anything like me & can't live without your false lashes, get yourself to Superdrug and stock up!
