How prices actually work

Retail pricing is designed, not accidental. These guides explain the mechanisms behind what you see on a shelf and on a product page — so a price becomes something you can read rather than something you react to.

Where to buy it cheapest

What actually drives the price in a category, and a check you can run on the thing you are looking at right now.

Kitchen

Small appliances where the consumable, not the machine, is usually the real cost.

Large appliances

Where delivery, installation and the cost of running it outweigh the ticket price.

Vacuums and floorcare

A category where the model code hides which attachments you are buying.

TV and audio

Retailer-specific model numbers make like-for-like comparison genuinely hard here.

Phones, tablets and computing

Contract totals, storage tiers and trade-in credit all hide the real price.

Watches and wearables

The phone in your pocket narrows the field before the price does.

Gaming and toys

Thin hardware margins, so shops compete on the bundle rather than the price.

Smart home

Check what the subscription costs before you compare the hardware.

Cameras

The mount you buy into outlives several bodies.

Furniture and home

Measure the route in, not just the room.

Garden, DIY and motoring

Seasonal stock, so when you buy matters more than where.

Sport and outdoors

Fit decides this before price does, and sizing is not comparable between brands.

Personal care

Consumables: the replacement heads cost more than the handle.

Baby and child

Compatibility and safety come before price in this one.

Comparing the shops

Who is actually cheaper, and on what.

Sales and timing

When a sale is real and when it is decoration.

Check before you buy, not after

Paste the link to anything you are about to buy. Bargn checks whether it is sold cheaper somewhere else, and whether something just as good costs less.
