Amazon’s Prime Day continues to gain competition from rival retailers piggybacking on the annual event with their own sales. Ahead of this year’s Prime Day, RetailMeNot had forecast that this year’s sale would see competition from 250 retailers. Today, the firm upped this figure to over 300, saying it found that more retailers than earlier estimated have decided to run their own counter-sales.

As of 9 AM on the second day of Prime Day — Tuesday, July 16, 2019 — RetailMeNot says it has counted over 300 unique retailers running Prime Day-related offers. This is up from the 275 retailers it had uncovered yesterday afternoon, and up from the 250 it had forecast.
