I don't think the sentiment is weird at all. One of the best things I got out of school was the ability to search out credible resources on my own and continue my own education (albeit a bit stunted without structured guidance.)

They usually cost around $75-100 USD, so ₱200 seems way low. I'd expect something between ₱2,500 and ₱5,000. I took a look through some of the listings on Shopee and there are a bunch of things about "raffles", which just sets off red flags for me.
