I just got back from Tower Records 'round here, and if you are looking to fill in some gaps, replaced scratched discs or explore a bit more inexpensively, they have some good stuff on sale. I picked up these for $7.99 each:

Kinks :: Village Green Preservation Society
Bill Withers :: Best Of Comp
Bruce Springsteen :: Darkness On The Edge Of Town
Van Morrison :: Moondance

Also in the bargain bins with prices from $7.99 to $9.99 were:
Neil Young :: Harvest
Neil Young :: After The Goldrush
Neil Young :: Everyone Knows This Is Nowhere
The Replacements :: Pleased To Meet Me
Mars Volta :: De-Loused In The Comatorium
Pixies :: Doolittle
Pixies :: Trompe Le Monde
Shitload of Modest Mouse

LINK to the website, this seems to be the selection, but I didn't see all of these titles, naturally. There's also a $9.99 Sale.

Doves, Some Cities can be had for $9.99 also, and there's a good bit more in the bins that I can't quite remember.

Tower Records, GWU branch, filled my hole when they barred me from entering any TR location for eighteen months, following an attempted grifting [sic] of a Tito and the Tarantula record. I abided the ban, though not with so much difficulty since there are no TR franchises in Milwaukee (and the closest is Chicago, to which I never get), and since its end have sworn never to go to one of the stores by choice either. So, I will not take advantage of your street-teaming offer, mmmkay.

All this talk about filling holes is giving me an obner.
