Internet service provider O2 is offering consumers the chance to pick up a pay-as-you-go dongle for half price until May 31st 2010.

For the remainder of this month, web users can buy a mobile broadband modem for just £9.99, as opposed to the normal price of £19.99.

Casual internet users, or those planning a journey away from home, may be particularly interested in the O2 MF100 USB Modem, which allows them to get online from any location.

The product is compatible with both PCs and Macs, and comes with a 30-day happiness guarantee - if a customer is dissatisfied with the dongle, they can get their money back.

Consumers can pay £2 for a single-day 500MB usage allowance, with one-week 1GB mobile broadband costing £7.50 and one-month 3GB priced at £15.

All three pay-as-you-go tariffs come with unlimited wireless broadband access.

Last week, O2 took over the front page of the Metro newspaper to promote its broadband and home phone services.
