Legal Question in Business Law in Texas

Re: How do I cancel a contrat I agreed to by a fast talker

From the Pa. Attorney General's website (http://www.attorneygeneral.gov/consumers.aspx?id=294):

"Pennsylvania law recognizes that consumers are particularly vulnerable when salespersons approach them in their homes, and provides additional protection for contracts that consumers agree to after being contacted at home. Contracts for goods or services in excess of $25 that are entered into as a result of a contact at your home, either in person or by telephone, can be cancelled within three business days following the date of the contract."

"In all cases, you must be given a copy of the contract, along with a Notice of Cancellation. This notice must include the date of the contract and the seller's name and address. Your cancellation must be in writing. Mail it to the address provided on the Notice of Cancellation, making sure the envelope is postmarked before midnight on the last business day (either the third or the fifth, depending on the services) after the initial transaction date."
