Why pay 10 bucks for a 7oz tube of mustard?

Because no American mustard even comes close this stuff is really hot clears your sinuses out and tastes fantastic whereas French‘s mustard and even gray Poupon have virtually no taste at all consider the difference in taste between Bud Light and Guinness and if you can’t relate to that then better off to stick with the French’s!

Can the glass jar be reused as a drinking glass?

Absolutely. I purchased this mustard especially for the glass jar. I have a small collection of glasses and glass mugs that had previously held mustard and this fits in perfectly.

Delayed shipping common?? Dont state what you cant deliver

I would say delayed shipping is not common. At least not until recently (COVID-19) when most shipping companies became backlogged due to higher volumes and less staff.

Does it need to be refrigerated after opening?

Technically it doesn’t, but we do refrigerate because we order in quantity. Also occasionally we have gotten a tube that is weeping so we routinely refrigerate.
