San Francisco-based Instacart isn’t ready to cede an inch to rival Amazon in the battle to bring groceries to your home.

According to a new report from Bloomberg, Instacart has raised a fresh, whole-range, grass-fed round of $200 million in venture capital. The funding comes just a few days after reports that Amazon is testing delivery from the Whole Foods stores it swallowed last year.

The new funding reportedly values Instacart at $4.2 billion and comes less than a year after the company raised $400 million at a $3.4 billion valuation. Instacart has now raised $900 million total.

The founders of Webvan could not be reached for comment.

In addition to Amazon’s delivery from its Whole Foods stores, customers in some select cities can get delivery from restaurants and local grocery stores via Amazon as well.

Instacart works with third-party grocery stores, with major partners including Albertsons and Costco. Worth noting, according to Bloomberg: Whole Foods is also a partner and investor, having backed Instacart before the Seattle crew came knocking.

In an interview with Bloomberg, Instacart cofounder and CEO Apoorva Mehta said: “We raised it because we want to win.”
