It's a very good question. Personally I think the stock gets crushed. It is one of the most overvalued companies out there right now as it is. However, SPSL is very profitable compared to AMZN overall sales right now. That is why I think they would be better off acquiring them instead of going toe-to-toe.
To answer your second question, not only do companies not like getting multiple packages & shipments for an order, they down right HATE it. AMZN isn't going to be rewarded mega Fortune 500 contracts anytime soon the way it is operated now which why they will need to make some drastic changes if they are serious about competing in the OS segment.
Staples was a GREAT company about 7 years ago. IMO today you have invested in a company with a pretty secure 3% yield and that is it. The company is out of ideas. In 2010 SPLS traded at $24 or higher. The team of Sargent / Miles have brought you an $11 stock. This is a disgrace. They should have been fired but I am sure they will be on the next quarterly conference call with more no new ideas. Key management people are leaving is another bad sign. There are much better places to invest than SPLS IMHO.
Stop comparing apples to banannas, do some DD. I know glass is half full carry on buying spls make sure you buy on every dip so you can average it down to $3 and then go long. Be honest tell us how many bags you holding. I am not so smart I am holding few bags too. We are all in for to make money basically we are both losers house wins. Period IMO
