1 day late on a verbal agreement = buyer is out of luck, deal is off UNLESS buyer can provide a tracking number for a check or USPS MO payment, and the shipper caused the delay.
Buyer should thank lucky stars seller is still willing do deal with a flake/deadbeat and that the snakes are still available for sale. Remember, the seller still has to feed and care for those snakes so a several week delay is more money out of the seller's pocket.Seller now weeks later does not want to add the second snake at no cost but instead offers you a good deal on it because it proved to be something else instead of a normal in the almost two months since the deal was first talked about. Obviously buyer would be mad they didn't get the free snake now that it turned out to be a mutation but seller says no money down and missing the agree deposit date means theres no more agreement and offers very very low price for said second animal but wont just add for free anymore.
What would you do being either buyer or seller? How long do you feel a talked about deal should last?
As the seller I would have marketed the snakes and gotten them sold to the first person who could meet my terms, which do not include stringing the deal out for weeks without payment. If I offer a payment plan it includes a non-refundable deposit and buyer signs a payment contract with all terms, payment schedule, late fees, etc. laid out.
