Canceling a Door-to-Door Sale
If the salesperson provided you with the right forms, you can cancel the sale by signing the form titled "notice of cancellation," dating it, and mailing it back to the salesperson. To obtain a full refund, you must do this before midnight of the third business day after the sale. Keep a copy of the form.
Even if you miss the three-day deadline, your sale may be void if the salesperson failed to make certain disclosures or if certain other conditions are met. See Tex. Bus. & Comm. Code Ann., Sec 601.201. But remember, under your 3-day right to cancel you must cancel in writing. Be sure to keep a copy of the contract and your letter notifying the seller of the cancellation.
