I asked Campsaver why I hadn't received their March Coupon and I mentioned that we were discussing this at BPL. This was their response ;
You might check to see if it was caught by your email filter. At any rate, the coupon promotion has concluded and the sale has ended. We apologize for the inconvenience.
There was nothing in my Spam filter. I was about to order $50 worth of stuff , but I think I'll do it somewhere else, as I've been getting 20% 0ff at some places, price matching at others and Bing Cashback.
