Buying everyday products online: criteria to avoid unnecessary purchases

Buying everyday products online saves time, especially if you have a family, a dog, a coffee machine or simply want to equip your home. However, a well-presented product page does not guarantee that the item will genuinely meet your needs.

The most common mistakes can be summed up in three pitfalls:

  • Relying solely on marketing claims: “high quality”, “smart” or “maximum protection” are no substitute for clear, verifiable specifications.
  • Overlooking dimensions and compatibility: a poorly fitting helmet, incompatible coffee pods or a bag that is too small can quickly become unusable.
  • Underestimating maintenance and running costs: batteries, recharging, replacement consumables, cleaning or shelf life after opening can all push up the final cost.

For more confident purchasing, it is therefore better to compare the technical specifications, usage instructions and context in which the product will be used.

Specifications to check before ordering

1. Size, capacity and compatibility

Size should be measured, not guessed. For a motorcycle or bicycle helmet, measure your head circumference, then refer to the manufacturer’s sizing chart. The MY 936 helmet, for example, pairs size M with a head circumference of 57 to 58 cm, while the DKONI HS-086 bicycle helmet offers size M for 55 to 58 cm.

The same care is needed for accessories designed for dogs. A reflective vest should match your dog’s chest circumference without restricting its movement or breathing. The Petgravity interactive ball is designed for medium-sized dogs and should always be used under supervision, particularly with animals that tend to chew their toys.

For a backpack, check the capacity in litres, the overall dimensions and whether it has a compartment suitable for your laptop. The Eastpak Out Of Office offers a capacity of 27 litres and a padded compartment for a 14-inch laptop.

2. Materials, safety and stated standards

Materials provide information about the intended use, but they are not a guarantee of unlimited durability. A ball with a chew-resistant rubber core may be suitable for regular play sessions, but it should be removed as soon as any part starts to come away.

For protective equipment, check the marking and standard directly on the product and its packaging. The MY 936 motorcycle helmet listing mentions ECE R 22.06 approval. Nevertheless, check that the required regulatory marking is actually present on the helmet you receive, and make sure the fit is correct before every journey. After a significant impact, a helmet must be replaced, even if no damage is visible.

Wall-mounting strips also require careful attention to the stated limits. The 3M Command multipack specifies a maximum load of 5 kg for the medium strips and 7 kg for the large strips on certain smooth surfaces. These products are not designed for wallpaper or fragile surfaces.

3. Consumables, storage and frequency of use

For coffee beans, compare the origin, roast level, strength and net weight. KIMBO Aroma Gold is made from 100% arabica and sold in a 500 g pack. It should be stored at room temperature, away from heat and moisture.

Coffee pods have a different priority: compatibility with your machine. Senseo Classic pods are designed for Senseo machines and are sold in packs of 40. After opening, the manufacturer recommends consuming them preferably within the following weeks and protecting them from moisture.

For Asian food products, check the allergens, best-before date and storage conditions. Wei Liang medium-grain rice is sold in a 5 kg bag and should be transferred to an airtight container after opening. Angelo semolina contains wheat and gluten, while Patak’s mango pickle contains, among other ingredients, mustard and has a high salt content, as stated on its product page.

  • Asian food products: check the ingredients list, allergens and storage conditions before completing your basket.

FAQ

Is it cost-effective to buy everyday products online ?

Online shopping can be worthwhile for products sold in multipacks or large formats, such as 5 kg bags of rice, coffee pods, toothbrushes or incontinence products. However, compare the price per kilogram or per item, without forgetting any delivery charges. For perishable products, consider your actual consumption to avoid waste.

How can you avoid choosing the wrong size when ordering ?

Measure the relevant area with a flexible tape measure: your head circumference for a helmet, chest circumference for a vest or your waist for incontinence products. Then compare this measurement with the chart supplied with the product, rather than relying solely on your usual size.

How can you extend the useful life of the items you order ?

Follow the storage instructions, clean accessories according to the guidance and check their condition regularly. Recharge electronic toys with compatible equipment, keep coffee and rice away from moisture, and replace any safety equipment after an impact or if there is visible damage.
