Less than a dollar

What could we buy these days with less than a dollar? I found an EXCEPTIONALLY CHEAP compilation of the Platters yesterday after a lunch and tea with my friend. Who is the Platters? If you had watched Stephen Chow's "A Chinese Odyssey" before, you would remember a compelling song sung by Law Kar Ying (the monk). Yes... "Only You". It was originally performed by the Platters in the 1950s. The CD only costs me $15 but I could enjoy over 18 songs with fine qualities... less than a dollar for one song! I also bought another compilation of Gerry and the Pacemakers, a popular British band in the 60s, for $45. May be you could go to that chain store in Tsim Sha Tsui and try your luck.
