After shipping cost to USA addresses, it comes to $11.85 per notebook. Seems a little bit lower than the $13 from gouletpens, for example, but only $1.15 difference per notebook, or a 9% discount, considering that this is a 5-pack and gouletpens offers singles (there's not infrequently a discount per bulk orders with some vendors). But the latter can be ordered at any time in any quantity and will arrive quickly. Would be better to see a greater discount here, considering these are 5-packs. In addition, many on-line stores offer free shipping over certain purchase amount promotions, so I didn't add shipping cost. At least right now there's a $5 off $50 promotion at gouletpens for signing up for their mailing list.
