I have no idea. Every time I have tried, which is like 5 times, they always said to me donations only. Also, Cayes aquarium off of 136th and Division will give store credit depending on there stock at the moment as well.
The Wet Spot doesn't pay for any. I took mine to World of Wet Pets in Beaverton Area. They give store credit and have a decent selection of saltwater products.
Thank you to SPSChampion and Hayes for coming by! I have edited the pictures and the corals underneath that are still available!! If anyone is interested I’ll be happy to make a deal!
