Best tip or piece of advice from a Gransnetter?

Earlier this year I put a post up asking for people’s feedback on spectacles and wearing varifocals for first time.
One post recommended going to Asda for glasses as they have on going offer of circa £70 for frames and lenses complete. Plus, if you have a second pair, you get a further £40 off.
I’m thrilled with my glasses, the service and the price!
Thank you for the advice!
What would you like to say “ thanks”
for?
