Gigabyte Store Accidentally Marked down Motherboards Too Low

Trying to understand it from the seller’s and buyers POV. They are a retailer on Amazon and I got an email about my order warning me I may not get my items as the seller is “”inactive””. Today it looks like the sale was only supposed to be -7% off and not -51% off lmao. What happens behind the scenes for the seller? Are they not obligated to fulfill the sale?
