Andersen patio doors from dealer or HD same?

[w_cohen]

I am looking for plain white vinyl replacement patio doors from Andersen. A local window dealer who deals with the major manufacturers of Andersen, Pella, Marvin, etc quoted me a price of $891 for a PSW510.

Home Depot seems to have the same model but I know how some manufacturers, at least Andersen, make a similar but not quite exact model to be sold only at HD or Lowes.

Anybody know if the two are identical? I sent off an email to Andersen customer service to find out.

The model at HD is PS51 OR/OL Kit. #2562132, part # 4757076, UPC 1628957588 for $649.

Thanks,
Walter
