$39.99 for 4-Pk ELEGOO PLA PRO Filament

Amazon is offering the 4-Pk 1-kg ELEGOO PLA PRO 1.75mm Filament (Black) for $39.99 with free shipping. This is essentially a match of the previous deal at $40, with a minimal price difference and no significant discount increase.

While the current price is very competitive, it does not represent a notable price drop from the last time this deal appeared. The deal has a good reputation, with a deal score of 30 and positive comments.

Given the current offering matches the previous frontpage deal, it remains a solid option for filament but doesn't provide additional savings or a better deal than before.
