Not really,
cgw/vpost per 0.5 kg rate is $3 after ave 20% card discount + 5% cashback/rewards, but with base rate of US$11
65dg is $4.50 /500gms. with no promo/cashback payment modes, but no base charge. (currently 15% off for BF period only).
Accounting for other fuel surcharges/insurance costs, the breakpoint is 4kg (under 4kg, good for 65dg). Thier website/declare/payment system a little more hassle too.
My personal guideline:
small consolidated shipemnts <S300 - CGW/hsg (gst on whole shipment CIS)
medium consolidated shipments >$300 - vpost (gst on single item CIS only)
small single/few items (total under 4vkg : 65dg
catch ball?
iirc , they are positioned more for expat re-location , good for big/bulk furniture/effects shipment. Our peanuts parcels not worth and ex- with them.
My calculation turns out quite different? Cheapest I can find is vpost using citibank, per 500g, (0.72+0.19)*5*0.8(citi discount)*0.95(cashback)= ~S$3.45
65 daigou is after 15% discount, $3.83.
Volumetric weight, vpost goes by /5000, 65daigou is /6000. Even with 1.1x chargeable weight for 65dg, vpost is still about 9% higher in volumetric weight overall. If we assume half the packages are volume dominated (likely most packages are), we can take it as 4.5%. Accounting this way, vpost is $0.23 cheaper per 500g. Break even point would be 20.6kg.
Factor that in free repack, accounting volumes in 10g instead of 100g, 65daigou definitely is cheaper. CGW/HSG even more ex. If I find 65dg service is acceptable, my CGW prime can throw away liao.
Even after BF discount is over, HSG 10% off + OCBC 6% cashback and 65dg no discount, I calculated break-even is 6.5KG (6% fuel surcharge, 1.3 exchange rate BEFORE fx fees, 50% volume dominated). factor in free repack for first 2KG savings, cumulative weight, I think 65daigou is likely to be cheaper in almost every scenario, unless you are orders are all large or very heavy items.
