Wow.... guessing game.

Shop A offered me package (ByWP and lens) at $880 with Hoya progressive lens 1.53 index. Nothing more.
I never know what grade of Hoya lens, never know what the frame price and after discount price. I tried hard to asked them at least tell me more about the Hoya lens but I was told they will let me know after the sales is confirm. I told them let me go back and think very hard about it and worked out my budget.
Your guess about the frame price that I paid based on $420 with discount of 10% or even at 20% is still high price. Now I am already disclosing it too much. Take that I got a very good discount even without bargaining further. I hope they did not made a mistake of giving me that low price. Anyway somehow I already paid $50 deposit with them.
Let say at $420 - 10% off or even 20% off ... it is still relatively lower price compared to other shops that I went to. It was also my first time with the shop and I was amazed by their service. The shop carried wide range of designer eyewear. They have Lindberg, Mykita, mostly high end brand. It seems their prices for the frames are reasonable.
