Tigerprint - Gift boxes?

Another interest of mine is packaging, and as I was looking through M&S I found it lacks in supplying gift boxes, I found just one set online. Seeing this as a niche in the market I thought about creating a possible giftbox line for M&S, creating a range to suit all sizes and shapes, occasions and sexes. Packaging alone isn't enough to make up the brief, so I was thinking about producing a creative advertisement piece for in store, using the idea of boxes, to promote the new product line.
