Big Rectangular PVC planter boxes
 

Anybody seen or know were I can get some big 3’ Or longer by at least 18” high and deep PVC rectangular planter boxes? I looked Walmart, Lowe’s, Home Depot, can find small window boxes, very large pots, but no large rectangle shaped ones. Lowes does have cement ones, but the are so heavy I can’t get them in my trunk or get them back out? I know I can go online, but would really like to look at them before I buy.
