@Tutanota I heavily recommend Swiss Galaxus Digitec -- https://www.galaxus.ch (or https://www.galaxus.de for Germany, https://www.galaxus.nl or https://www.galaxus.fr etc) --- more details https://en.wikipedia.org/wiki/Digitec_Galaxus

Two major example of why they are good: https://www.galaxus.ch/en/page/real-purchases-real-reviews-galaxus-and-digitec-reset-rating-system-42750 (see what you have bought, inc budgets etc) && https://www.galaxus.ch/en/page/how-dynamic-pricing-at-galaxus-works-39120 (transparant pricing history per article)

And mostly their pricing is pretty spot on and their support great.

@Tutanota I wrote to Tuta when neither my reset code nor the QR could help me retrieve my account. Deafening silence.

@Tutanota trying to buy from local shops as much as possible 😀

@Tutanota have you heard of http://galaxus.de

@Tutanota Kaufland has a pretty good marketplace that you can search before you go to Amazon …

@Tutanota
In Germany you can also use Conrad.de for all kinds of technology.

@Tutanota Please add OLX to Polish column.
www.olx.pl

@Tutanota allegro is great. I don't think they do real estate (to be fair, I never tried), but you can find pretty much everything else on there. Shipping is often free with allegro smart (their Amazon prime).

@Tutanota I've used Cdiscount a few times. Also, it can be good to take into consideration sites for second-hand goods, which have the benefit of having a lower carbon footprint. In France, the primary site for that purpose is "le bon coin".

@Tutanota Otto supports also austrian delivery

@Tutanota A very nice alternative to find local shops is @lmaa !

@Tutanota hi Tuta. Emag is also available and very much used a lot in Bulgaria as well!
