When people asked for a low priced Sequential Discovery puzzle so they could try out examples of the genre, the trilogy of Unsafe Deposit, Bolt Action, and Mighty Pin were what people highly recommended at the time. Unfortunately, they aren't being produced anymore which is a shame for the newcomers to the puzzling world today. However, it still stands as the prime puzzle to recommend as a "gateway" puzzle into the Sequential Discovery genre!
Unsafe Deposit is the first born child who excels at everything and makes their younger siblings look like slackers and gets way too much pressure from the parents to have grandchildren asap. People see it as the classic and best of the series. It's hard to comment on it without giving away too much, but it makes for a delightful SD as the solver works on moving around the coin and deducing what is going on inside the box.
Alan couldn't ship out copies with USA quarters internationally due to restrictions on
shipping currency, however it was only an issue for him because he would otherwise send out hundreds of them.
I can send an international shipment with a quarter in it without issue for anyone who wants this puzzle.
I accept and prefer using Zelle as my payment method of choice.
I
accept Paypal. I prefer Friends & Family due to the IRS tax rules.
But if you rather pay with Goods & Services, I will accommodate that
preference.
I accept Wise for international buyers.
I am willing to consider other payment methods.
Shipping is USPS or UPS
Buyer chooses the shipping service and shipping speed, First Class or
Priority (assuming the package is under the weight limit for First
Class).
Insurance is optional, but buyer has to cover it if it is desired.
I ask the winner to hold off on paying until after I calculate and
message final shipping costs to be added to the final bid.
