Glasses direct offers

I see these offers come along regularly, the current one looks good but I really want 2 pairs of sunglasses, the current deal means that will cost £14 plus £15 per pair for the tint so it totals £44. I seem to recall in the past they did an offer at the start of the summer for 2 pairs of sunglasses which may work out cheaper, does anyone remember what the deal was the last time they did this? Do they do it every year? Are they likely to do it again this year?
Thanks
