Looks like there ARE a few stores in Paris selling Cheerios.
The pricing appears outrageous to me, but then I am thinking/shopping US, so what do I know.

Tell you friend I said 'hi & you're welcome'

A word of caution: there are 2 varieties available in Europe
- General Mills Brand of Cheerios, 280g or 396g box for 7€ or more, this is what we buy in US and
- Nestle Brand Cheerios, 375g box for 4€ to 5€, this is a "UK/Europe" item

Last time I checked Nestle and GM were different companies, so taste of these 2 products could well be drastically different.

You'd have to figure out which option is going to be more financially wise:
- pay over 7€ per box in a Paris store
or
- buy in US for $0.00 after coupons, plus international postage
or
- go the "friendly FT'ers" route
