So I'm doing math on the diamonds:


 * 20 @ $1.99 = 0.0995 per diamond. At this rate the following is true:
 * 60 diamonds would cost $5.97, which means that they are 5/6 of the original price, not a 20% discount. Instead it's 20% of the final cost has been removed from the original cost. It's also a cost of $0.0831666... per diamond.
 * 250 diamonds would cost $24.875 (or $24.88 when rounded to a penny), which means that they are 4/5s of the original price, not a 25% discount. Instead it's 25% of the final cost has been removed from the original cost. It's also a cost of $0.07996 per diamond.
 * 550 diamonds would cost $54.725 ($54.76 rounded), which means . . . that I don't feel like doing the math, but I suspect the math is the same and that it's not a 37% discount and instead removed 37% of the final cost from the original cost. It's also a cost of $0.0727090909... per diamond.
 * 1500 diamonds would cost $149.25, which means that they are 2/3 of the original price, not a 50% discount. Instead it's half of the final cost has been removed from the original cost. It's also a cost of $0.06666 per diamond.

Now, on to some of these. They all say the discount is the same, so I'm curious.
 * 180 would be $17.91.
 * At $4.99 this is a rate of 2.772222... per diamond.
 * At $7.99 this is a rate of $0.043888... per diamond . . . you are definitely paying for the convenience of 14 days instead of 28 for the one above.
 * 400 would be $39.80.
 * At $9.55 (current conversion from 499 Philippine pesos) this is a rate of $0.023875 per diamond.
 * At $10.07 (current conversion for 36.99 AED) this is a rate of $0.025175 per diamond.
 * At $12 (conversion made by someone else for Czechia) this is a rate of $0.03 per diamond.
 * 850 would be $84.575.
 * At $19.99 this is a rate of $0.02351... per diamond.
 * At $21.08 (current conversion from CAD) this is a rate of $0.0248 per diamond.

Those are the ones I saw and the info I could garner without too much effort.
