You'll find quite a bit of variation among different charts, and different recorded versions, in the chords to Cole Porter's "Love for Sale." I've often wondered which changes are actually "correct." Recently, I acquired a copy of the 1930 sheet music, showing Porter's original piano arrangement, along with chord symbols for guitar.
In sheet music of this period, it's usually better to look to the piano arrangement, rather than the chord symbols, as a guide to the composer's intentions. In this case, the chord symbols shown in the sheet music show harmony that is pretty close to the piano part, although the symbols do miss some bass lines and voice leading.
Below are the chord symbols shown in the original sheet music. I've omitted the introductory "verse," and made a couple of other small adjustments, such as leaving out a few bass notes indicated in the chord symbols (e.g., "Db/F"). Click to enlarge.
Although the sheet music almost certainly represents Cole Porter's original intentions, it is not entirely improv-friendly. Jazz musicians want to conceive of harmonies in terms that are more formulaic. A good modern chart would need some alterations. The best modern fake book lead sheet I could find is in the Standards Real Book(Sher Publishing Co.). More about this chart later.
The most glaring harmonic disparities between different versions, both recorded and printed, come at the beginning of the three A sections.
Here's what Porter's original sheet music shows for the first 8 bars of each 16-bar A section (each box is a measure):
For an excellent analysis of the interplay of words/harmony/melody in "Love for Sale," check out this article by Michael Buchler. (Incidentally, a footnote in this article quotes another Porter scholar, Matthew Shaftel: "Porter was personally involved in nearly all levels of his sheet music publication including the correction of proofs...so that the printed versions differed only superficially from his own manuscripts.")
Although Porter's placement of tonic major and tonic minor chords was exact and intentional, recording artists have treated the first 8 measures of each 16-bar A section in a number of very different ways. Several different interpretations are listed below (I am looking here just at the basic tonalities of the Bb and Eb chords, and am not discussing any added 7ths, 9ths, 11ths, or 13ths):
Sidney Bechet (1947), George Shearing/Wes Montgomery (1961) - These recordings "bluesify" the tune by playing every tonic chord as Bb or Bb7, every IV chord as Eb or Eb7. Bechet's was the first recorded version to use this interpretation:
Billie Holiday/Oscar Peterson (1952), Oscar Peterson (1953): Follows Porter except for the last A, which goes to Bbm both times:
Charlie Parker (1954), Ahmad Jamal (1955), Shirley Horn (1962), Dexter Gordon (1962) - These recordings resolve to Bbm every time. In Parker's recording, he resolves to a concert D note just once in his solo, for the fun of it, while the piano sticks with Bbm. Guitarist Billy Bauer does the same in his solo, with a "Jingle Bells" quote (the tune was recorded in December). In Dexter's recording, pianist Sonny Clark uses Bb or Bb7 through much of his solo. Here's the scheme:
Cannonball Adderley/Miles Davis (1958) - Seems to basically use all tonic minor chords on the head, going to all tonic majors for the solo. Soloist and rhythm section occasionally diverge from this pattern.
About commercial fake book charts: Different fake books show different harmonic interpretaions. You can play "Love for Sale" any way that you like, but don't expect different published charts to be compatible. Personally, I like the "Standards Real Book" chart. It sticks close to Porter's original harmony, adding sevenths to reflect modern preferences. Here is how Sher shows the first A section; compare it to the first 16 bars in the Porter chart at the beginning of this post:
The bridge from the Sher chart is shown below. Compare mm 45-48 to the sheet music chart above. The chords in the original chart may seem a bit irrational from the viewpoint of today's jazz players. The Sher chart shows a more modern, functional solution. Sher's version of these measures harmonizes the melody nicely, retains most of Porter's harmonic intent, and makes sense to improvisers.
To its credit, the Standards Real Book shows the introductory "verse" section for "Love for Sale." Unfortunately, it fails to show Porter's 8-bar tag at the end of the song. Most other modern charts skip both the verse and the tag, as do many recordings. The tag can be found in Dick Hyman's Professional Chord Changes and Substitutions for 100 Tunes Every Musician Should Know. Unfortunately, Hyman leaves out the verse!

It's hard to say which version I like best. Here's the Miles version, recorded at the "Kind of Blue" session in 1958. Wonderful playing by everyone, particularly Bill Evans:
