The Unemployed Philosophers Guild is running a headline offer of 15% off all orders, which applies to every purchase you make. This is the best starting point for most shoppers, though a few specialized bundle deals may work out better if you're buying specific items.
For small basket purchases under $10: You won't qualify for any of the percentage discounts except the headline 15% off all orders, so that's your best option. If you're just picking up one or two items, the 15% off all orders offer delivers solid savings across the board.
For purchases between $10 and $15: The 15% off all orders deal still applies and remains your go-to choice. At this spend level, the 5% off orders over $10 offer exists but is outpaced by the headline 15% discount, so stick with the larger saving.
For mid-range shopping around $20-$30: This is where bundle deals start to compete with percentage discounts. If you're buying four of the foam sweet foam little soaps, you can get them for $16 instead of full price, which may beat 15% off depending on the regular retail price. Similarly, the 3 sticky note booklets for $20 offer is worth comparing against the percentage discount if you want those specific items. For everything else at this spend level, the 15% off all orders remains your best bet.
For purchases over $30: The 15% off all orders is still strong and will be your primary option for most baskets. However, if you're buying the 3 pencil set, the $32 deal may be competitive depending on regular pricing. Again, calculate the final price with 15% off and compare it directly against the bundle price to see which saves you more.
Remember that only one offer applies at checkout, so you'll need to compare your basket total with the 15% discount against any bundle deals that match your items, then choose whichever produces the larger saving. Most shoppers will find the 15% off all orders covers all their needs, but those buying specific bundles should take a moment to do the math before selecting their offer.
