Bookemon's Back to School Special offers free USPS shipping on orders over $59, making it the main deal running right now. This applies to most shoppers regardless of quantity, so it's worth checking whether your order clears the $59 threshold before you buy.
The real value of Bookemon's current promotions depends on what you're ordering and how many copies you need. For a small order under $59, the buy 2 copies hardcover for $5 off deal is your best option if you're picking up two hardcover books—that's a guaranteed saving. If you're buying fewer than two hardcovers or just one item, the newsletter signup for special offers and promotions may be worth doing before you shop, as it could unlock future discounts.
For orders between $59 and around $80, the free shipping alone will likely save you more than the small quantity discounts. Shipping costs vary, but free USPS delivery usually works out to $5–$10, so the Back to School Special is your winner here. If you're buying 4 to 9 photobooks, the 5% off deal applies, but compare it against the free shipping: a $70 order of photobooks would save you about $3.50 with 5% off, versus $6–$8 in free shipping, so free shipping still comes out ahead.
For orders with 10 to 49 photobooks, the 10% off discount kicks in and becomes more attractive. On a $100 order of 10 photobooks, that's a $10 saving versus $6–$8 shipping, so the percentage discount edges ahead. For bulk orders of 50 or more photobooks, the 15% off deal is your sweet spot. A $500 order would save $75 with 15% off—far more valuable than any shipping saving.
Keep in mind that only one offer applies at checkout, so when you've built your basket, compare what the best available deal actually saves you. The free shipping threshold is easy to hit, but if you're ordering in serious bulk for schools or organizations, the larger photobook discounts make a real difference.
