Ever since I started working in 2015, I often encounter a salesperson from a company that engaged in lead conversion for its customers. They are almost everywhere I've been in my city. What they do is to sell stuffs and donate proceeds/profits from sale to the charity they are working with at that point. While this may not look out of place, the fact that they approach people with a slight lead of "helping charity" only to sell its products make me wary and try to avoid them. What they do is that they will have a short activity to get people to sympathize with their cause (asking to write made-up pet's name to vote on what necessities is important to it), then they will describe that they are doing CSR work for its company in association with the charitable organization. They will conclude the conversation by asking us to purchase products, and some salesperson outright saying that it's a donation (when in fact it isn't). They fix a minimum price of their stuff at $15, but they will try to get a bundle of $60, and when I say I don't have that much, they will keep dropping the price, as low as $3 (no stuff). With the minimum wage here is $10 a day, whatever they're trying to sell is just too expensive.
