Hi,
Wouldn't be able to specifically help with regards to these two models, but please think twice before ordering big expensive stuff online.
I'd suggest the following steps:
1. Go to three to four brick and mortar retailers and start your bargaining for your shortlisted models. You will get a fair idea of how much opening discount they are willing to offer on sticker price.
2. On the day, see prices online.
3. If they are really tasty, go back to shops and ask if they will better it.
4. Their first offer will be to match it, but not better it.
5. Final step, start getting them to quote their best, and keep playing them off each other.
6. There is a point where each retailer will tell you they cant go further, and that they are okay if someone else beats them.
7. This should be your final price. Then, take a call on which retailer you are most comfortable with.
For me, it was Vijay Sales, cos i have made many appliance purchases from them, and their help with anything to do with manufacturer contact has been superb over the years.
All the best.
