Passports, translation & explanation help?

Please translate and explain these passports [?]

Does this mean price change due to old stock, some kind of getting rid of old versions cheaper:

In my eyes this looks like a normal one, with sales stamp & sign:

Why does this one have double stampings, has it been repaired:

And why some passports are empty, no stamps nor signatures? Lazy sales people or why?

Hi Juhani,

the first two are just receipts of stores or warehouses, the crossed out price is probably just store's price override over the suggested retail price.

The 3rd one is the coupon for repair, one is from the factory I guess and one from store. Some are empty because they're coupons to be used for repair in case it breaks. I think that's how it worked.
