The paper and envelopes I chose were part of the ‘buy2 get 1 free’ promotion. I purchased 2 packs of paper and got 1 additional for free; I purchased 4 packs of envelopes but only got 1 additional for free as there was no more inventory. The store said there was no way to compensate me for the extra free package of envelopes I was entitled to. The sales associates were nice about it but I feel that Staples should have some kind of protocol for taking care of this kind of situation. An IOU? A credit towards my next purchase? But the paper I purchased is very nice and will suit my needs fine.
