Splurging At Warehouse Sales

We were at the Harvey Norman warehouse sale last weekend. We weren't really looking for anything but I noticed that they had very cheap electronics such as Mac memory upgrades, netbooks and all kinds of hardware for any computer fan. We were really tempted to pick up a wireless modem router but decided against it in the end when we were advised that it might be cheaper elsewhere. I do love warehouse sales but do be careful not to be caught up in an impulsive moment and splurge on things you might not need!
