Though there is a huge difference in the supplies included in the starter kit bundle vs the gemini jr on its own, as per their descriptions... Have emailed customer service to figure it out. If anyone here has insight on this, please do share!
JoAnn's customer service finally responded with the differences between the 2 Gemini Junior listings. Hope this will help other peas!
Article 15965304 - Gemini Jr. Multi-Media Machine - does have everything listed below in it. That comes from the manufacturer that way: 6 Thin metal cutting dies, 1 3D Embossing Folder 2 Clear cutting plates 1 Metal Cutting Plate 1 Magnetic Shim 1 Plastic Shim 1 Rubber Embossing Mat
Article 16426637 - Crafters Companion Gemini Junior Starter Kit Bundle - also has everything above PLUS 1 magnetic shim ( for a total of 2 ) and 1 cutting plate (for a total of 2 each). So the bundle ( 16426637 ) has 2 more items in it than the 15965304.
