Ya, I bought it in a Telus store, but before I even payed for it, I asked the guy to call up Telus for me so I could try and get some discounts. So I swindled my way to a small discount and also lowered my rate plan. I assume they become pretty flexible once they find out you're buying a brand new phone, so it worked out pretty well for me.
You can probably use the "I'm considering switching to Telus from Bell" line in order to get some lowered rate plans. It's a perfect time to bargain since every company is trying hard to get sales. And if Telus can take your business away from Bell, I'm sure they will do whatever they can to get you. Use that to your advantage
