I agree with Shotgunjones that things don't look good for Sidney. In any big merger, the acquiror is always looking for "synergies". There are revenue synergies and there are cost synergies. Cost synergies typically involve closing sites and laying off employees.
Prices at the combined company may go up in the short run. If so and if the higher prices last long enough, they will attract new market entrants who will seek to take advantage of the higher prices. This should lead to more competition and lower prices.
The Internet can be something of an equalizer. Razors are a good example. For years the market was dominated by Gillette and Schick and prices for the newest and best blades kept going up. Enter Internet companies like Dollar Shave Club and Harry's. Now I can get a month's supply of great blades shipped to me for about $4/mo and shipping is free.
