I've bought W65C02 chips from Jameco in the past, for reasonable shipping. But things have changed there. Now the only non-FedEx and non-UPS option seems to be "USPS International Express Mail", they don't offer USPS first class international anymore, which was a cheap and efficient option. Worse, they don't even let you know the shipping price anymore.. they state "Jameco will determine shipping weight and assess charges when the package ships". If I try to figure out via USPS what that will cost it seems to be in excess of $40, which is meaningless for goods costing less than $7 a piece. The last time I tried to order from there (and cancelled) the cost *was* shown, and was indeed excessive. Now the trick may be to get you to order, and then your credit card will be charged much more than you think.. later.
However, the OP is in Finland IIRC? ELFA (can be reached as elfa.se or directly as
https://www.elfaelektroniikka.fi/) sells the W65C02, DIP version, for around $16 - $17. Shipping from there may be excessive too, but they should at least be local.. or nearly so. For myself I'm in the situtation that it's possible to add my private orders to what my company buys and save on shipping, as we buy from there regularly.
(Finland also has a shop I've heard good things about - PartCo - but unfortunately they don't carry the 65C02).
