Ribble are normally my 'Go to' internet shop for cycling bargains. Not always the cheapest but normally the cheapest. They seem to be matching somebody else's 20% off clothing sale, not sure who but 20% off their already low prices seems almost too good to be true. I have bought loads of stuff from these guys in the past including groupsets and kit. Although i don't need anymore cycling clothes this looks like my best chance to get a set of the Assos S7 knicks.
Bear in mind that these guys have free shipping over around $100 AUD. Also make sure that when you open the page you change the little flag at the top right of the screen to Australia (this subtracts the UK VAT from the price) then change the currency from pounds to AUD. Bit of a pain but makes it easier to compare. Also watch out for add-ons. i bought a pair of Assos knicks and there was a 'drop-down' that gave the option to buy a tub of Assos chamois cream for an extra $2. All up my S7 Knicks (only bought the Neopros) and cream cost about $144 delivered, be struggling to get Nalini Knicks in the LBS for that!!
Wiggle has TDF-1 for 15 pound off clothing too
