Yeah I've seen it as well, but you have to buy it there then ring up to find times/spaces, I thought about getting it then going in to ask but if they say it's 2 weeks wait (look how many they've sold on groupon) then I'd rather pay a bit extra to have it sooner. Plus I can't really use the Ipswich branch anymore after I argued with the tech doing my tracking which way was toe out was....needless to say the tracking was worse after he'd done it! 
So far cheapest I've found locally is F1 with a discount code for £40, but to order that online have to wait until weds now, want it done for the weekend really so might go in and ask if they're not busy and want cash for the weekend lol...
