A quote from this Official Walmart Announcement, "If customers find a lower advertised price, we’ll match it at the register."
So yes, you can bargain with Walmart's prices. Not to mention using coupons or buying from a lower priced store.
Taxes are not something that is sold and is incomparable to "Make an Offer"
The Post Office is in competition with UPS and other delivery services, often times UPS will beat USPS rates on larger packages. And I never knew the Post Office set selling policies for everyone. This example is nonsensical.
Used Car Dealers Haggle, very true. A good friend of mine runs a Used Car dealership. A crook he is not.
All you have done is given examples of certain companies/industries. Using this method you would have to explain every single item on eBid, and how "Make an Offer" on that specific item causes a loss of integrity.
Please just try explaining how "Make an Offer" causes a loss of integrity on this item http://us.ebid.net/for-sale/vintage-...0-43902261.htm
This item has a Book Value of $2000 and it is listed on eBid for $975, if the seller had the option of "Make an Offer" maybe he accepts $850. How does this cause a loss of integrity?
