Halfords Trade Card for Forces - MoneySavingExpert.com Forums
Halfords trade card is one of the best discount cards going. They have never entered the trade market before and are aggressively lowering there prices to beat all competition. I am a mechanic in the Army and I had the full brief from one of there card suppliers. If you can get one without showing any quals then get one while you can because they are not meant to be to non mechanics and they could tighten up in future.
The card doesnt give reductions on the push bikes etc but huge savings elsewhere. They also send through discounts about every 2 months. Here are some examples that I have had:
Discount voucher: Halfords diesel oil £10 This is good quality oil and was for 5 litres which is enough for a complete oil change on most cars.
Trade card: I went for the best quality battery that they do for my 2 litre deisel. This was a calcium one and is guaranteed for 4 years. Original price £100- trade card got it for £50
New wiper rubber, should be £8.00 came to £2.50 with the card.
My advise is to get one while you can because once you got one its yours forever. Yep, thats right, no expiry date, they are good for life. Yahoo!
Discounts vary, but just google them, they do offer it on tools, so will be handy for anyone leaving and wishing to become an Engineer in Civi street as their proffessional range is very good, I buy the odd cheapies to modify to suit jobs, and don't mess up my Snap Off stuff with angle grinders..
