3. An enforceable contract requires both parties’ signatures. This really doesn't jive with what I know about contract law, so I checked the article, and it is more specific: An enforceable contract requires both parties’ signatures: Under existing law, any contract for the sale of goods worth $500+ must be evidenced by writing; Pepsi did not sign anything. Still, was Pepsi really selling something for more than $500? It's an exchange for Pepsi points (not cash), and even though you can buy them, are they equivalent to cash? Also, on top of that, has anyone signed anything the last time they bought a $500+ laptop, PS5 bundle, unlocked cell phone, etc.? I know a contract has to meet all elements of a contact to actually be a contract, so the other 2 reasons are enough, but this 3rd reason seems out of place, given the situation and even what I learned in my contact law class.
