You are correct 100%. To respond to Hikeeba's comment directly, we do apologize for the initial confusion on this - it should have been presented in a more clear, precise manner. Do note, however, this this was promptly resolved per your feedback. We are always listening and whenever necessary, we always step in and make things right.
Regarding the shipping cost - that is not a fair nor equitable comparison, as our cost per deck is nearly HALF of that on other retailers. I trust that you would much rather pay a reasonable, realistic shipping cost than spend twice as much for the same product.
If you need an apples to apples comparison, our cost on 60 decks of normal Bicycle's is $113.40. The cost on Ellusionist (the site you mentioned) is $179.40. That's a difference in cost of $66.00. Shipping them cross country (domestic) on theory11 would be around $12.50. Meaning you would save $53.50 - and that's if they were offering FREE shipping. Hope this puts things into a bit more perspective.
