Okay. I am always in the exchange forum. Lately, other exchangers always outbid me with their offers. I'm thinking that if I'll raise my offer, I'll get the item but I don't know if i'll get profit in it. I decided that I should offer immediately my final offer. Is that right?

What final prices/offers will make the sellers accept it & i'm going to have profit?
Example : Should it be 50k less than the LMP/ABP? Should I take off 10% of the LMP?

If so, what final offer will be decent for me & the seller for items 100k and above? 200k and above? 300k and above? 400k, 500k, 600k, so on and so forth.
