My wife and I just joined Direct Buy, but now we want to cancel. How many days does one have after signing contract if you want to cancel?

I think only 5 to 7 but I don't know what all contracts that applies to.
I heard that they are a big rip off partly because of all their fees and inavailability.
To make it worth your money you would have to furnish your entire life around them.
Cancel asap but check any consequences for cancelling.
