Consumers now have less than a week to take advantage of O2's latest dongle offer.
All this month, the UK broadband provider has been offering its pay-as-you-go mobile broadband modems for an initial fee of just £10.
However, the half-price offer expires on Wednesday March 31st.
The O2 USB Modem E160, which is available in either a pink or black model, comes with a 30-day happiness guarantee.
Depending on the level of usage individual consumers expect, they can choose from daily, weekly or monthly tariffs.
Both PC and Mac users can take advantage of the device, which may reassure Apple customers concerned about connectivity issues.
Last year, Electricpig.co.uk reported that some consumers were experiencing difficulties finding a dongle compatible with the Snow Leopard operating system.
