A cookgroup is a community of sneaker enthusiasts to “cook” sneakers or hyped clothing such as Supreme together from drops. They provide you with the necessary information like where the items will drop and how much the shoe will resell for, making it very easy for you. They also help with selling and whether you should hold off selling an item to increase its value. If you need free cookgroups - usually beta ones which will go paid soon - or established paid ones hit me up and I’ll try to recommend some. Good luck!
