RE: [PSUBS-MAILIST] Venting an ambient sub
Hi David.
I will fish out the dome later and see how much it will be to send to you. I dont think it will be as much as $70. Its quite large but not very heavy. Anyway, i'll let you know and you can send me the money when you have it.
James

James,
That's great! I am working on a budget that won't budge. I live in Jackson, Tn. in the U.S.A. zip code 38340. Is there any way to determine the shipping costs? I can scrap up enough within a month if it is say $70.00 or so if that would be ok.
