ToJoin I'm afraid you've strayed straight into the lions den. From what I understand of Tropic it's about £75 to join and you get a variety of products in your starter kit. You can do one of two things with these - use them and get to know the range for yourself so you can decide if they are any good and you want to continue to retail these, or you could just simply retail these on and make an instant profit. Obviously the best way to make retail sales is to showcase your products by personal use, as any business not just MLM would do. My advice if you treat this as a hobby it will pay you like a hobby and mostly hobbies do end up costing you money as the very nature - hobbies are not usually free unless it's a walk in the park. However if you take this a little more seriously with structured times for working, and by this I don't mean scrolling through Social media or spamming people then you could make some commission based income. Do read the threads before you sign so you have an informed choice, MLM is not for the faint hearted it is a business, it is hard work and not everyone makes money from it. Done properly with the correct attidude and approach you should be fine. Not everyone joins for money either you may be surprised of all the other benefits you get from it, social aspect, training etc - which can be useful in any business. Sleep on any info youre given don't sign up in haste really give some thought to what you are looking for and what you are prepared to work for.
Just to provide the other side opinion you were looking for before they turned on you, dehumanised you and called you out as disingenuous good luck what ever you decide. In or out most MLM genuinely don't care as it's not for everyone.
