The 1000 samplers happened last year around this same time. They had made an error in the number of samplers requested and couldn't return them.
Since you want to get 5 of those perfumes listed on the sampler box, I recommend checking out the prices of the perfumes you want. See if your desired perfumes are over the $75 price of the sampler. How much is the larger bottle and whether there are any perfume gift sets. You should be able to use the voucher on the gift set too.
Do not buy the sampler if the perfume choice you want is less the cost of the sampler. Since you want 5 of the perfumes... you will probably purchase a sampler or more and therefore you will have those perfume samples. Those samples are only 1.5ml. Only the $95 sampler has bigger samples.
