Is Black Friday actually the cheapest time to buy?

For some products yes, for many no. It is most reliable for technology and seasonal goods, and least reliable for everyday items. The check is the same as any other day: the ordinary recent price, and the price at other retailers right now.

Should I wait for a sale to buy something I need now?

Usually not for small purchases — going without and holding an open decision often costs more than the saving. For larger, postponable purchases, waiting is more likely to pay.

When do technology prices drop most?

Typically when a successor is announced rather than during a sale event. If a product line refreshes on an annual rhythm, the period just before that refresh is the worst time to buy.

When to buy without guessing

The right time to buy depends on which of three categories your purchase falls into.

Advice about timing purchases is usually a list of months. Buy televisions in January, garden furniture in September, and so on. Some of it holds. Most of it is too general to act on, because the thing that determines whether waiting pays is not the calendar — it is what kind of product you are buying.

Three kinds of purchase

1. Products that get cheaper as they age

Technology, mainly. A model launches at its highest price and declines from there, with a sharp step down when its replacement arrives. Waiting genuinely works, and the largest single drop usually comes when the successor is announced rather than during any sale.

The practical move: check whether a refresh is due before buying near the top of a cycle. Many product lines update on a predictable annual rhythm, and buying the month before is the most expensive time.

2. Products with a season

Anything with a natural buying period gets discounted once that period has passed, because storing unsold stock costs money. Garden furniture after summer, coats in spring, decorations in January.

Waiting works reliably here. The cost is that you must buy the thing when you do not need it, and store it until you do.

3. Products with no cycle

Everyday goods, consumables, most household items. There is no reliable pattern to wait for, and waiting mostly means going without. For these the answer is not timing but comparison — the difference between shops on any given day exceeds the difference between weeks at one shop.

The sale events

Large discount events are genuinely useful for the first two categories and mostly noise for the third. The reliable approach is the same whichever event it is:

Decide what you want before the event. Wanting a specific thing and finding it discounted is a saving. Browsing a sale and finding something you now want is spending.
Note the ordinary price beforehand, so the discount is measured against something real.
Check the price at other retailers during the event, not only the one running the promotion.
Accept that some items will not be discounted, and buy those when you need them.

The cost of waiting

Waiting is usually treated as free. It is not:

You go without it for the whole waiting period, which was presumably worth something or you would not be buying.
Prices can rise. Waiting is a bet, not a guarantee, and it is a bet you lose when supply tightens.
Stock runs out. Particularly for end-of-line goods, where the discount and the disappearance arrive together.
It occupies attention. A decision left open keeps costing you thought.

For a small purchase, the cost of waiting frequently exceeds the saving. Buy it, compare it properly on the day, and move on.

The one rule worth keeping

For anything you can postpone, set a watch and let something else do the monitoring. For anything you cannot, compare across retailers at the moment of buying. Almost every timing question resolves into one of those two, and neither requires knowing which month is best for what.
