If you're buying or selling online, the Calgary Police Service wants to make an offer.

CPS says people can now use its district office parking lots as safe spots where items purchased online can be exchanged for money.

Police believe their parking lots, which are under surveillance at all times, may deter illegal activity, though officers will not be directly involved in any exchanges or negotiations.

"Online classified and auction sites have been used as a tool to sell stolen property to unknowing victims, and can present a safety threat," reads a release sent out by CPS today.

In the past, criminals have used sites like Kijiji to facilitate illegal activity, including violence in some cases.
