My first post so go easy....
Right now Optical Express are offering free laser eye surgery consultations (which includes a free eye test as well as the actual consultation), plus £4.50 cashback for booking through Quidco.
Also, book before 28 December and get the surgery (iDesign plus LASIK, best procedures available) for £2,795 instead of £4,200 usually (33% saving). Thereafter £2,995 until end of January. If you want to use your glasses prescription instead of their state-of-the art iDesign procedure (which effectively measures your eye prescription at 1,200 different points within your eye for best possible results) then it will cost less. And similarly if you get LASEK treatment instead of LASIK.
Also, the price includes a 20/20 vision money back guarantee on the procedure and 0% finance.
You could go to some dodgy places that will charge you less still - but they probably won't have the same reputation as Optical Express, and I'd be surprised if they offer the 20/20 vision guarantee as well. I certainly wouldn't gamble on my vision with those places!
