Here's a review on King Charles' Highgrove Jam, from Real Housewives' Recaps. I Bought King Charles' Highgrove Jam (None Of Meghan's Scam Jam Here!)
Never tried those. Do you have to buy a kit? The Bonne Maman® brand preserves and jams are good too. And the shape of the jars is a bonus---to store things in. Similar to those.
No minimum orders that I read of. I just enjoyed watching the video. I can get into a jam, without any problems.
