I've been trying to figure out what the current "exchange rate" (vs. 2009) might be for US Dollars against Entrecard credits. I googled, and came up with results like "From my transactions, I would have to value entrecard credits at around $3.30 per 1000 entrecard credits." Another individual "...went on e-bay and purchased 10000 entrecard credits for 35 dollars! so we're looking at $3.50 for 1000..."
Here's a link for ya ::: What is the DOLLAR VALUE of Entrecard credits... any suggestions or calculations on this?
