Bargaining at the Big Stores

There's a little known fact that most are not aware of: that big electrical department stores can be rather flexible with their pricing.
A few neighbourhood stores are well known for having much lower priced electrical appliances than the recommended retail prices usually displayed on large electricals chain stores.
Here's a strategy that we took:
1) Large electrical chain stores are good showrooms. You can also ask the sales persons for details on each model, and take back a brochure or two.
We've encountered some pretty good sales people at Best Denki Taka, Bishan, Harvey Norman Millennia Walk who are rather patient and know their stuff.
2) Call up neighbourhood stores and ask for best quotes
3) Go back to a few select electrical chain stores, and see if they can match or better these quotes
*tip* Harvey Norman stores at a particular IT mall or convention centre seem to be pretty competitive *ahem*.
4) Take the best deal (package them to reduce transportation fees or hassle).

Even with such well thought out plans, there are always Wild cards in a UNO deck.
The recent IT show gave an unbeatable price for our TV because of useful vouchers thrown in as freebies.

Dang! You can't plan everything.
