Scruffy, I am definitely in. You will be hearing from me.
Since we are looking to deliver the gift after Christmas, why don't we decide on a cutoff date for donations? December 23rd? That gives us 4 weeks from today.
Also, since the gift certificate will be in Euros and most of us are in the US, the conversion rate will apply.
The nerd in me just had to look up the EUR/USD FX daily chart.
The USD looks most likely to strengthen against the Euro to the end of the year. Right now it costs $1.10 to buy 1 Euro and maybe will improve a penny or two by the end of December, but it's going in the right direction.
