Going to a big shop, you might have a field day or a bad day, cuz you dunno who will serve you.
Could be a highly experienced long time staff or a part timer working on vacation.
The experienced guy can reason with you whatever product on display, make better sales decisions and assure you. But the part timer just want to close the sale, so will say anything just to do so.
I'm sure the product in question will be priced to reflect the condition on the sale item.
One thing about buying things is not to be rash, patience will bring results. Talk with the sales staff, if he cant help, get him to bring a senior staff to you.
You patience could land you a very good deal, cuz they also want to clear that last piece which is hanging there for ages already.
Of course if you are that free, hang around there often and get to know their senior staff, sure will be rewarded with discounts and freebies in future.
That's unless the company has very poor managment and sale policy in the first place, then my suggestion is not to waste anymore time there, look elsewhere, sure to find something which suits you.
