Popular products, such as LCD and plasma TVs, were sold or secured for pick up in store at up to two per minute at the busiest times on the company's website.
The strategic decision by Comet.co.uk to launch its January sales campaign online on 25 December resulted in sales on Christmas day increasing 700% year-on-year.
The biggest online sales week recorded was the week commencing 23 December, the first time it has been this late. Historically, sales peak the week before, depending on the last delivery date before Christmas.
The top selling web-generated products were the Nintendo Wii and Tom Tom satellite navigation systems pre-Christmas. The Samsung 40in HD TV at under £700, and the HP £399 2GB Pentium Dual Core laptop with 15in screen were the best sellers on Boxing Day.
