I would "run the numbers" again!
Even with the 50% off at Gurneys, the cost per lineal foot comes out EXACTLY the same, figuring in the extra Gurney's Delivery charge, while none at Burpee. I calculate it to be $4.40 per vertical foot of cage (5 ft. for the Gurney's, 6 ft. 4 in. for the Burpee).
Add in that the Burpee cage is a heavier gauge galvanized steel, and it is a no-brainer to go with the Burpee product. And they are in stock (just ordered 8 more of them). I also found out that Gurney's charges your credit card the day you place the order - - even if the product is back-ordered and does not ship for another 2 months!!!
That should be illegal, in my opinion.
So, do the Math and you all decide what is best for your particular needs. Just want to make everyone aware of the (better) alternative.
