Price and “discount” tricks to spot
A big discount feels like a win. In window sales, it’s often the whole point of the pitch — a number designed to look generous rather than to be genuinely cheap. Here’s how the common tricks work, and how to judge a price on its own merits.

Anchoring: the trick behind most others
Almost every discount trick relies on anchoring. The rep plants a high number first — the “full price” or “list price” — so that every figure afterwards feels like a bargain by comparison. If the starting point is invented, the “60% off” that follows is meaningless. What matters is the final price against a fair market rate, not against a made-up one.
The classic discount plays
- The manager’s special. A phone call to head office that magically halves the quote. A genuine price doesn’t need a performance to justify it.
- The sign-tonight saving. A chunk knocked off if you commit before the rep leaves. Real quotes hold long enough to compare.
- The show-home discount. Money off for letting them photograph your finished job. Usually just a reason to close.
- The bundle blur. Windows, doors and extras rolled into one number so you can’t see what any single item costs.
- The deposit sweetener. A better price in exchange for a large upfront payment — which shifts risk onto you.

A trustworthy quote is itemised and calm. You should be able to see the number of windows, the frame material and colour, the glass specification, the guarantee length and the fitting cost — without a stopwatch running. Prices vary with your home, the style you choose and your region, so the single most useful thing you can do is know the rough going rate before anyone quotes.
Spend a few minutes reading up on double glazing deals and fair pricing and on the typical cost of new windows and how to cover it. Walk in with a ballpark figure and no anchored “full price” can move you.

Savvy test: ask the rep to leave the quote with you at the same price, in writing, for a week. If they can, it was a real price. If it vanishes the moment you don’t sign, the “discount” was the product.
Where the money really goes
It helps to remember what actually drives a window price, because that’s what a discount is supposedly cutting into. The big factors are the number and size of openings, the frame material and finish, the glass specification, any special shapes or colours, and the labour to fit and make good. None of those change because a rep phones head office. A genuine, better price usually comes from a leaner business or a quieter month — not from a “manager’s decision” made on your sofa. So when you hear a figure drop sharply, the useful question isn’t “how kind of them” but “what was the first number for?” The answer, almost always, is nothing at all.
