In my country we have a voucher company that sells gift vouchers on behalf of many small merchants, including chains. I small voucher company might have 200 merchants.
I emailed one of them and asked if they would accept bitcoin. They emailed back and asked for more information, so I sent them a link to Bitpay online payments and explained that bitcoin is widely accepted in Switzerland, South Africa, and Slovenia, and increasingly in the US. I gave a lot of supporting links, and described how our community could offer exposure to these merchants and increased sales volume through their platform, and add all of their merchants to btcmap.org. I also linked to bitrefill.com. These merchants would have no overlap with bitrefill, they are too small and the margins in the voucher business would be tiny.
Has anyone tried this is their own country? Are there risks in not considering enough?
