Paypal have been sending round an e-mail to their customers, and for PC gamers it's something to be interested in. If you use Steam that is, as many do.
The e-mail contains details of of Steam's upcoming Autumn sale, and according to it, it will commence this Wednesday - the 26th and will run through until the beginning of the next month ending on Monday December 1st.
The e-mail itself was an advertisement for PayPal as a medium for buying up Steam Wallet codes:

If you wanted an excuse to buy some games for yourself soon, or you were hoping to get friends and family digital copies of games for the upcoming present-giving holiday that is Christmas this is your chance to get some good deals.
Remember to wait for the discount to be big before you commit to buy!
