The seven biggest mistakes when shopping online

1. Too many of the same item

You think you only ordered one pair of sports socks, but find a ten-pack in your letterbox. That’s because some products are only sold in multi-packs.

Tip:Before hitting the order button, check the relevant quantity in the product information.

2. Wrong format

You order new storage jars to keep your kitchen cupboard tidy. However, the delivered US models are two centimetres too short for Swiss spaghetti.

Tip: Read the product information carefully and make sure that you select the right size. Standard sizes may vary depending on the country in which they are made.

3. Unfortunately incompatible

Your new hoover brush fits nicely between the slats of your heater, but not on your hoover. Your new drone also remains stubbornly earthbound because the control app isn’t compatible with your mobile phone.

Tip: When buying accessories and electronic devices, make sure that they are compatible with your existing products or systems. Check the product information to find out which models are compatible and what technical requirements apply.

4. Unsatisfactory performance

You expected a lot more light from your new LED lamp. And you slam your new notebook shut in frustration because an operating system hasn't been installed on it.

Tip: Check the product information for performance details as well as what is included. Check the lumen value for lights: a lamp with more than 1000 lumens (lm) provides more brightness.

5. Not as pretty as in the photos

Your sandals looked like they were a mocha colour in the product photos. But they seem somewhat green on your feet in natural light.

Tip: Check if there’s any customer feedback on an item. This will give you a better idea of what it’s like - for instance, with regard to the appearance or the quality of the material.

6. Mix-ups

All keyboards are the same, right? Unfortunately they aren't. At the very latest when you try to type ‘apéritif’ with the correct accent, you’ll realise that you’ve ordered a German keyboard.

Tip:Make sure that a product meets the Swiss standard.

7. Wrong size

The blouse is too baggy, the jeans too short and the bike helmet too loose: it's tricky ordering clothing and sports equipment in the right size, even if you know your exact measurements. Sizes may vary depending on the brand or country.

Tip: Compare your body measurements with the provided product information. Based on customer feedback or your order history, many online retailers will suggest which size is the best fit for specific brands.
