And if you don't want to wait for a sale, the regular prices at the British and Irish sites are usually better than sale prices at the US ones, even after the shipping, which is sometimes free. Try ProBikeKit, Ribble Cycles, Wiggle, Chain Reaction Cycles, etc.
As for tires, I live in the city and work in da 'hood. The last thing I want is a flat in the rain in front of a crackhouse. I run Continental Grand Prix 4-Season tires on all my bikes--25mm on three of them, 28 on the fourth. My experience with them has been excellent. They're just as puncture-resistant as Gatorskins (which I ran previously), but they ride a lot nicer, they're lighter, and they have incredible wet weather grip. Ordered from Britain or Ireland, they're about $42 each.
My commute takes me about 7 miles through da 'hood - 4-seasons FTW. I run 28 mm foldables on my commuter and I second everything above. 3 punctures in 2500 mi. Another thing - I can install them on my Roval rims bare-handed, no need to mess up my manicure.
Gotta try ordering from Brits. Pricey things, these tires. On the other hand - I trust my life to two contact patches size of my thumbnail, better make them count.
