Office product company Staples.co.uk has been knocked offline by the popularity of its own discount voucher codes. The UK website became flooded with traffic after a £20-off voucher code appeared on several popular bargain-hunting sites, including HotUKDeals and the MoneySavingExpert.com forums.
The £20-off voucher code – which did not require a minimum spend – allowed customers to claim up to £20 worth of items for free, leaving only the delivery charge to pay. Although the code could only be used once per customer, several users successfully bypassed that restriction by placing several orders from multiple accounts. Larger discounts and free delivery were available on more expensive items by adding one of several other voucher codes on top of the existing £20 reduction:

It is not yet clear whether orders placed using these vouchers will be honoured – order confirmations have been emailed to customers, but such orders remain subject to approval.

The demand continued long after they were sold out, with some TouchPads being resold on eBay for more than twice the original cost.
The Staples UK website became responsive once more around lunchtime today, following the deactivation of the original £20-off voucher code:
