> Wallmart does not prohibit your product from listing its wholesale price on the label.

Are you sure that they don't? I honestly wouldn't be surprised if Walmart does have clear policies around prices of any kind being printed on packaging. And it wouldn't be a stretch to assume that if they have a policy, it would disallow printing of any price which is less than the highest price Walmart intend to charge at retail.

Unless you can show such a policy, it is reasonable to assume it does not exist. I surely have no way to prove otherwise short of finding complete list of all policies. A good indication is that neither of us heard about it so far.

If we have no evidence, it is not "reasonable to assume" anything.

Meanwhile, I'm merely saying that it wouldn't surprise me if such a policy exists, whether formally or informally. The distinct lack of any product on Walmart shelves which has a below-RRP price printed on its packaging is strong circumstantial evidence at the very least.

It is reasonable due to the Occam Razor.

The fact that you mentioned is an extremely weak evidence in the light of very thin margins Walmart has (under 3%), which is more than 10 times less than the old store tax, with probably even smaller incentive to combat.

Listing wholesale prices on the product is vanishingly rare, possibly nonexistent. I wouldn't be surprised if it infuriated retailers to the point that they refused to stock your product.

Printing MSRP on the product happens all the time. Arizona Iced Tea is a prominent example.

Rarity of example os irrelevant. Producers have no need for that, because IRL stores generally do not have 50% markup on mass produce.
