I am a former TDS CM and current WDW CM. I was still working at TDS when The Children's Place took over in November. All CMs get 30% at both TDS and TCP. There was talk about TCP buying another clothing store, but I'm not sure if that ever happened. There are a few of my former co-CMs that float around this board, so I'm sure they can answer that discount question.
I can however tell you what TDS CMs no longer get. Gone are the discounts at WDW. No hotel discounts, no discounts on passes and no free entry to the parks. TDS CMs can call in advance and get up to 3 passes a year to WDW, but that's it. They no longer get 2 passes every 6 months like we used to. Also, there are no discounts on merchandise in the parks and on disneydirect.com and no discounts on restauarants at WDW.
I'm sure that now TCP has had a little while to get things organized, there will be more perks within the company.
