my situation is like this:
I wanna buy this guitar pedal for my own personal christmas present, but and i want to ask for a lower price. i kinda already told him i'm interested in buying it from him, however, i didn't actually say i'd buy it yet. so what can i do to lower the price? at the moment, it's going to cost 150$. it goes for 150$ on ebay.

You contact him and offer a lower price. What the fuck do you think? Email him and be like...

"ur pedel is awesum i really want it dog but like i don have enuf of dat sweet cash money so liek i waz thinkin i cud giv u like 125 and we cud call it even, wut u say homes?"

You get my point.

Offer oral sex.

*copies and pastes it into the email*

i gave your mom oral sex earlier today.

Simple:

You "jew" them down.

Pretend you have an offer from somebody else that's slightly cheaper but you want to buy from the classified instead as it's less hassle so want the guy to have an oppertunity to match the price/you think this seller is cooler and want to buy from him but ultimately price is the biggest factor.

Beware that if they decide they won't drop the price then you have to swallow your pride and buy from the first guy with him knowing you lied about another seller.

Alternatively just outright say that considering the quality, you think his price is a little optimistic. Be polite.

HURR HURR HURR

STFU new arrival

You're only supposed to say that to acolytes. Don't scare off new blood in Totse!!

Shut the fuck up, or I'll rip your mothers throat out with my bare hands jam it on my dick and use it as a condom to fuck you in the arse with.

Hope he has a totse account and reads this and feels sympathy, or just explain him your situation and be all like, "Hook a nigga up, homeboi" so he can think your black and poor so he will lower the price. Unless he is racist.
