How do I display the current currency symbol in text that I wish to display on the Checkout and Shopping Cart Pages

Currently is says ...

Please note: Your Shopping Cart Sub-Total does not include 3.00 postage and handling which will be added at the checkout.

What I'd like it to say is ...

Please note: Your Shopping Cart Sub-Total does not include $3.00 postage and handling which will be added at the checkout.

The code for the current bit looks like this ...

define('TEXT_INFORMATION', 'Please note: Your Shopping Cart Sub-Total does not include ' . MODULE_SHIPPING_FLAT_COST . ' postage and handling which will be added at the checkout.');

So what do I need to put before . MODULE_SHIPPING_FLAT_COST . to include the selected currency symbol.

I tried . MODULE_CURRENCIES_SYMBOL_LEFT . MODULE_SHIPPING_FLAT_COST . but that doesn't work.
