The Shrimp Tank- Kudos

I recently ordered Salty Shrimp GH+ 230g and Salty Shrimp GH/KH+ 200g from these guys. I checked out and the next day I got an email from them apologizing for not being current on inventory count for the GH/KH+ 200g. They offered a refund or an option to ship the smaller 85g GH/KH+ and then send the 200g when it was back in stock. I chose the last option because I needed the minerals. Today, I got the 200g container in the mail. No charge for the 85G jar. Shipping was fast both times.
