Sorry if this has already been posted.
Thanks to Portal and Andrewr22 on MSE I have just bagged 2 pairs of prescription glasses for £18 delivered.
Originally the glasses I went for were priced at £15 each but reduced to £10 in the sale. With the purchase of two frames you get free p&p (normally £3.95).
Using a 10% off code: carole
This reduces the price to £18.
And don't forget 14% quidco.
