UK: Should Go to Specsavers

I got an interesting little booklet from Specsavers UK through the letterbox today. It had details of a few offers and discounts I didn't know about, as follows:

• 2 for 1 on any of their designer glasses that cost between £69 to £125 (excluding safety eyewear)
• Their monthly contact lenses start from as little as £5 a month and their daily disposables from £16 a month
• If you pay for the lenses by direct debit, you can also get half-price designer glasses
• All glasses in their kids' £64 range and teens' £85 range are free with an under-16s' NHS optical voucher
• Under 16s also get a free NHS eye test
• And yes, as you can see from the picture, if you actually have the booklet, you get a £5 eye test voucher.

And on their website, they actually have links to lots of other offers: http://www.specsavers.co.uk/offers/
  
 Hmm, it is about time I had an eye test...
