Frequently asked
Honest answers before you buy.
I only need one or two of these — should I still buy the bundle?expand_more
If you only need one book, buy that one — they're individually priced from S$19–S$49. The bundle saves money once you're buying 3+ books, or if you anticipate needing the others within 12 months (which most readers do — CPF and tax decisions interact, HDB and CPF interact, retirement touches all of them).
Are the bundled books the same as the individual versions?expand_more
Yes — identical content. The bundle is purely a pricing convenience. Each book's workbook is also included unchanged.
Do the annual update memos apply to all four?expand_more
Yes. You get the January CPF / IRAS / MOF update memo, the quarterly HDB grant updates, and the February pre-tax-season memo for as long as you own the bundle.
Can I gift the bundle?expand_more
After launch, yes — Gumroad supports gift purchases. For now, message us if you want to gift to a family member during the waitlist period.
Refund policy?expand_more
7-day no-questions-asked refund on the entire bundle.
