I've been looking at powerline networking and found this D-Link promo. There's a few other deals running in the link as well.
Buy the power line kit DHP-P309AV (contains two adaptors) from participating stores and get another DHP-P309AV kit free via redemption/claim.
- Must purchase before 30-June-2017
