When should I pick the Cocolis delivery method ?
If you wish you to use the Cocolis delivery method, your seller must have added it on the advert of the product. If he did, then you just have to enter your zip code on the ad page or in your cart to see the option appear.
The price of the delivery is calculated with the dimensions of the product and the distance between your seller and your delivery address. It will show like so :
It can happen that Cocolis doesn't appear, unfortunately it can be because of your delivery address : if it's not on a road with a lot of traffic, Cocolis won't be available.
