This is the email this company sent me after 4 days, cant understand why they would wait so long to send me reply when i paid them on a friday morning at 02.32 in the morning. Tried to call countless time but all u get is answering machine. then they sent me an email with a higher shipping price when on there website it quotes 80 shipping now they want to come back and try to hit me for 184? Mind u all of this could have been avoided if they had put down that they only ship to cali customers for 80. whats weird is  paypal only charged me 760 total including shipping, these clown tried to hit me up for 184 for shipping? what kind of business are they running? tryin to extort more money from hard working customers. i would never do business with them any more, and encourage everyone to steer clear of them, very poor people skills!!
