Ron Paul often says he's careful not to waste money from his presidential campaign donors.

A peek into his final 2011 campaign finance report shows the extent of the Texas Republican's frugality -- or at least how detailed the congressman is when it comes to filling out these reports.

USA TODAY's Gregory Korte found 164 separate entries for expenditures of $1 each in Paul's report, which was filed yesterday with the Federal Election Commission. Gregory says that's the most $1 campaign expenditures for any GOP presidential contender.

Paul bought value meals at a McDonald's in New Hampshire, a truck stop in Iowa and a Circle K in Kansas. He bought three pieces of music through iTunes and office supplies from a Dollar Tree store.

The most $1 expenses, however, probably helped Paul the most.

The reports show he paid 102 separate tolls on the New Hampshire Turnpike. Paul came in second to Mitt Romney in the Granite State -- the best showing to date for the Texan.
