It’s significantly harder to shop there, especially as an American. I found the same products I would get on Amazon to be 2 or 3x the price when I would shop in stores or online there excluding VAT and exchange rates. Maybe it allows more competition? But it surely isn’t an easier, cheaper experience in general. And as far as not being a Swedish speaker(which many people in Sweden are not), online shopping is even harder because the e-commerce options there tend to primarily work in Swedish, and have limited or no English support
Amazon.de does free delivery to Sweden, but it is not next-day of course.
To me the idea for ordering toilet paper online is a bit foreign. In order to collect the package, I would have to go to my local store, where they already sell toilet paper.
