My first post woohoo.
Choose the delivery option and follow checkout to near the end where you input voucher code. Type in voucher code HALTTGB and then press your BACK button on IE and go back to where you choose delivery or reserve and collect. Now check the reserve and collect button and then continue like normal, you have now reserved a tomtom V3 for £99.97. Ive just done it now and collected it. But hurry last night the price was not this low!
