I'm sure the price of oil has something to do with this... Because you need oil to make plastic, and there's a shortage of oil so plastic cost more?.... wait what's that? oh... oh there's a surplus of oil? we have wayyy too much oil? oil costs a lot less than ever in the past 10 years? oh ok... I'll just shut up now...
I think it's safe to just go and blame Isis for these prices.
Maybe TRU's been following scalper prices on kijiji and ebay for their masterpiece figures and decided to just cut out the middleman and get the money themselves.
