New cashback deals! Including the 60mm that I know a few people are after.

I'll echo what king says, the 45 is a cracking lens for the money, but you'll need the dedicated 60 for macro, but that will be on for portrait albeit slower.
Family just ordered the 60mm macro for my Birthday but it was before the 1st October.
Bad timing!
Might be worth returning for that £75 even if you can't get the cheaper prices from some online retailers.
