Zinc is sold out at my local CVS type stores. It is mostly sold out at Amazon or on a delivery delay of two weeks. Not much ZINC selection at ebay.
BUT here is an available zinc and a bargain:

Just chop up a penny. Copper coated zinc
And of course zinc gets credit being what kills Covid after HCQ weakens its defenses.
I don’t recomment buying any supplement on Ebay.
Same with the off marketplace sellers, on Amazon.
Buy ONLY from a reputable source, many online drug stores, that have been around for years.
