Free shipping

Hi everybody,
I'd like to know if is it possible to have (automatic) free shipping when your subtotal is upper than a fixed value ?

Excuse me for my poor english....

The same in french (it's more easy for me...) :
Bonjour à tous,
J'aimerais savoir s'il est possible d'avoir des frais de port gratuit lorsque l'on atteint un certaine somme et ce, sans l'utilisation des coupons.
En fait, c'est pour offrir les frais de port lorsque la commande dépasse les 100€.

Thank you in advance

There is no specific module but it may be possible, to trick the weight based shipping module to do this by using the same value for weight as you use for price in your product. It sets the freight price to zero when it runs out of defined values. ig 0-3kg => $4, 3-8kg => $7, >8kg => $0

There is some info in the forums about how to define the ranges but I haven't used this module myself so can't comment further.
