$$$ - Currency

I think that really means the USA Many places that previously posted prices in $ now charge the same in Euros especially in EE. The dollar zone is shrinking and even where the $ is taken, locals see its value when they change it & adjust accordingly.

The US is now very competitive as it is following (whether deliberately or not) the old method of letting the $ fall. This effectively wipes billions off its foreign debt as its value decreases. In effect this is a present from all of us who hold $ reserves to uncle Sam by way of its economic clout. The only problem is that dear uncle Sam should watch out as the new kid on the block, the friendly Euro is looking ever more friendly and stable and is making inroads. It might even take over as world currency unless the US stops living beyond its means.

As imports to the US rise and old stock is sold off, prices in the US will rise eventually. The traditional rule of thumb is a 6 months decalage (time until prices catch up from the decrease in value of the $)

So the time to go is now & in the next few months.

Many other countries also use the US dollar or are pegged to it. This includes most of the Caribbean as well as Latin American countries such as Ecuador
