It's not just the price.
Donald Trump's team are trying to cash in on the success they had with the red 'Make America Great Again' baseball caps that dominated his presidential campaign.
In celebration of St Patrick's Day (or St Patty's Day as they insist on calling it) the Trump committee have launched green 'MAGA' hats.
At US$50 (€47) the hats are double the price of the original red caps.
But that's not the main issue.
Twitter users were quick to point out that the "alternative" shamrock embroidered on the back of the hat is a four-leaf clover.
The clover has nothing to do with St Patrick's Day, or Ireland.
The shamrock is a three-leaf sprig of clover and is associated with St Patrick's Day.
The four-leaf clover is a plant, that's rarer in abundance. It's also a sugary, oat piece that's usually found in a box of Lucky Charms cereal.
