Orwin, owner of a used furniture store, gives Maggie a signed offer to buy her living room furniture for $800. This offer:
1) is revocable without consideration because it is an offer to buy rather than to sell.
2) is revocable at any time because no consideration was given.
3) is irrevocable for a reasonable time, not to exceed three months, even if there was no consideration.
4) would have been irrevocable if Orwin were a merchant, but he would not be considered a merchant under the UCC.
