This is a bit late, like 3 years, but better late than never. 4 years ago my home burned down. I lost everything except my 2 dogs, thank the Lord. I have a pond and I always kept it running. Considering there was no hydro, I bought a generator. It died, so I took it in and required a rental. I went to the AMAZING people at Agra. I rented one from them. A few hours later, that was stopped. I called and went back to get a replacement. It worked great! I had it fir 3 days, when mine was ready. I took this one back and asked the fella what my bill was. He said, and it still brings tears to my eyes, "You've been through enough, just please put a review on Google ". I finally had my home rebuilt and have been here barely a year. I would HIGHLY recommend Agra. Not just for their products, but for their compassion and integrity. Thank you to all of you that made it possible for my pond not to freeze!🙏

I recently had the pleasure of using this company for 5yds of mulch for my garden beds. I was shocked at how much cheaper they were compared to your Supersacs/Big Yellow Bags. I easily saved around $800. Delivery options were very flexible, and their driver perfectly placed the mulch exactly where I had hoped without us even being home to direct.
I wouldn't use anyone else, to be honest.

Thank you to George and Kyle for your help with my order. I would also like to thank Moe for his excellent customer service and expert placement of 6 yds of mulch.
I will be back for any further gardening and landscaping needs.

The site was easy to navigate and select what I needed and when I had questions Matt Penford guided me and was very helpful in assisting and was quick to respond through the whole process.
I would highly recommend them.
