Section 430. Duty of buyer

1. Except as provided by subdivision four of
  section four hundred twenty-nine,  within  a  reasonable  time  after  a
  door-to-door  sale  has  been cancelled or an offer to purchase revoked,
  the buyer upon demand shall tender to the seller any goods delivered  by
  the  seller  pursuant to the sale but need not tender at any place other
  than his residence. If the seller fails to  demand  possession  of  such
  goods  within  a  reasonable  time after cancellation or revocation, the
  goods shall become the property of the buyer without obligation  to  pay
  for them. For the purpose of this section, twenty days shall be presumed
  to be a reasonable time.
    2. The buyer shall take reasonable care of the goods in his possession
  both  before  cancellation  or  revocation  and  for  a  reasonable time
  thereafter, during which time the goods are otherwise  at  the  seller's
  risk.
    3. If the seller has performed any services pursuant to a door-to-door
  sale  prior  to  its  cancellation,  the seller shall not be entitled to
  compensation therefor.
