Maybe because Fellers prices are more than others?
We used to use Fellers for most everything. They were awesome. Order it today, have it tomorrow morning. Then we started getting 2-3 day deliveries. Needed some material the next day for a rush job, Fellers didn't have it, called Advantage (Merchant Member here), got the material. Looked at the invoice and found them to be cheaper than Fellers by 10% or so.
I'd like to order from Grimco, but I fight with their website. The "email my password" actually changes the password, and then I never get the email telling me what the new password is. It's not locked up on the server or hung in spam, it never gets here. So it changes my password and then I have no way to retrieve it. If I can't log in to the site, I can't place orders online. I've had a couple of issues with their website like that.
I also order standard "No Parking"
signs from them and they showed up a week after I ordered them, rather than a day or two. They may be great, but every time I try to use them, it ends up being a hassle.
