So they're the plastic ones and currently $12 over at amazon so to get free shipping maybe $7 2 cup brewer and 2x $8/100 filters, would take you a while to work through them.
Edit: filters are sold out probably not a deal any more, unless you're buying a kilo of coffee to get free shipping.
I use the daiso drip cup and the brown daiso filters. Is there a big difference in filter paper quality?
