But if I visit product page:
https://www.amazon.com/gp/offer-listing/B002KT3XQM/ref=olp_page_1?ie=UTF8&f_new=true
I see 13 offers.
Is it possible get all 13 offers?

Answer 1

The GetLowestOfferListingsForASIN call gives you one result for each set of so-called "Qualifiers". Your example shows three distinct sets of such Qualifiers:
Used-VeryGood->Merchant->True->0-2 days->90-94% for $32.99 (incl. shippng)
New->New->Amazon->True->0-2 days->98-100% for $34.27
New->New->Amazon->True->0-2 days->95-97% for $41.18
What is puzzling me, is that no new "Merchant" offers were shown, when I really think they should:
New->New->Merchant->True->0-2 days->98-100% would be a distinct fourth set of qualifiers.
What you really seem to be looking for is a different call: GetLowestPricedOffersForASIN returns up to 20 different offers for a single ASIN.
