Travelex Currency Services

Use Travelex if, and only if, you absolutely cannot wait to get in country, or make it to Denver where there are currency exchanges with civilized rates.
Dollar to Euro exchange was more than 12% off from the published rates on XE, and that isn’t including the $ 10 «service fee» — which perhaps would be acceptable if the staffer was even half way pleasant — which he was not.
$ 410 got me 316 Euros.
Don’t do it.

Terrible Experience.
Travelex was recommended to me by my bank but they turned out to have both an exchange fee and a terrible exchange rate. I was looking to get about $ 200 in yen; they charged me $ 210 dollars for 20 000 yen (about $ 185) plus a $ 10 exchange fee. That is $ 35 dollars in fees on only $ 200 of exchange (or ~18%).
If that wasn’t bad enough, they implied to me that if I brought unused cash back, I could exchange it and get my money back (except for the fee). so when it turned out that I could do everything in Japan with a credit card I avoided spending cash. When I returned with 10 000 yen (~93 dollars) they waived the fee but still used their terrible rates and instead of getting the $ 105 I’d paid back, I received only received $ 82.
The final total: $ 138 dollars for 10 000 yen ($ 93).
