Do not order from the PLC website. I ordered 2 of the vdw21-5g-01n on february 26 because the website said they have them in stock. A week later I get an email from them with a quote for the part that I already ordered. I contacted them to find out out what's going on and when they'll ship my solenoids and they said that they will probably get them from the vendor "on OR about April 1." Don't know what to do but wait since I already paid for them.
