Rahlfs edition Lexham Greek-English Interlinear Septuagint
I am considering purchasing Rahlfs edition Lexham Greek-English Interlinear Septuagint. But . . .
Problems:
1. Two same but different items
one (A): 149.95 dollars (https://www.logos.com/product/180798/the-lexham-greek-english-interlinear-septuagint-rahlfs-edition)
the other (B): 134.99 dollars (https://www.logos.com/product/3613/lexham-greek-english-interlinear-septuagint)
2. Comparison
Publication date: A-149$ (2009), B-134$ (2009-2010), but when I search newest one on Rahlfs edition, A (149$) appears first.
Alternate texts: A(149$) doesn't tell whether it includes them. B (134$) shows it includes them.
Product description: B (134$), the cheaper one has more detailed description.
3. Question
How come the two same products show different prices?
What's the difference between the two?
Which one should I buy?
