2020/2021 Postponed Brides: Have any of your vendors suddenly quoted you much higher after contracts have been signed? Supply chain issues?

Many contracts were signed in mid 2020, as my wedding was scheduled for June 2021. Everyone said, "Oh, we'll be back to normal by June 2021 -- no sweat." Well, of course it wasn't. And we postponed a year to June 2022 and ate the costs of the rescheduling fees, and the bumps in prices then.

Now, my florist (who did not ask for a rescheduling fee or anything, she just simply changed the date on the contract) wants me to rent all the vases from her as opposed to buying them outright, for the same cost as she previously contracted to buy them. This is not the biggest deal in the world, and her and I will figure something out. She later said she felt bad and that she would uphold the original contract price, but the floral supply chain has hit her bad.

But I'm concerned about all these other vendors who have quoted things, we've signed a contract based realistically around those prices, but because it was just a quote -- do they have any leg to stand on in terms of changing the prices? Has this happened to anybody else? How are you addressing it?
