In the Netherlands Grin can be bought easily at:

Maybe similar to how the Grin main website is and should list wallet software used/endorsed by the community, we should add a list of exchange the community has good experiences with.
Regardin your proposal for listing wallets @joltz, I would go for a complete list of all wallets since it is best to be able to show all information on the main site. However, I propose to give community and core team endorsed wallets a special status, e.g. ‘official wallet’, ‘community endorsed’ (Nifler), passed security audit’ (Grin++) or something similar. This is in line with how it currently is listed on the main website. Just give people all information we have as community so they can decide on their own.
