I have an item on my website (4 Pack Travel Bug specifically) that I cannot figure out how it is calculating the shipping after the customer places more than 2 of these in the shopping cart. The shipping costs actually go down!



Details:



Weight: 6 oz

Packaging: Large Box ($1.50 & 2 oz)

Packing Capacity: 99



Handling: $3



1 x 4 Pack Travel Bug: $2.36 (6 oz + 2 oz) + $1.50 + $3.00 = 6.86 (same as shopping cart, USPS 1st class rate)

2 x 4 Pack Travel Bug: $4.80 (12 oz + 2 oz) + $1.50 + $3.00 = $9.30 (same as shopping cart, USPS Priority rate)

3 x 4 Pack Travel Bug: $6.80 (18 ox + 2 oz) + $1.50 + $3.00 = $11.30 (shopping cart says $9.04, USPS Priority??)



4+ x 4 Pack Travel Bug: Same.... $9.04



Can anyone explain this to me? I would be very grateful. It just seems that more items should calculate for more shipping unless a flat rate is coming into play somehow.......



Thanks!
