ROBOTIME is running a Halloween Sale right now and the lead offer on the page is the $20 off voucher at the top of this page, valid on orders of $139 or more. That $20 fixed discount is best for shoppers whose cart reaches $139 and whose items are not eligible for a larger percentage sale on selected products. The page also lists smaller threshold vouchers, percentage off codes for selected items, and a number of sale and bundle discounts that can beat the voucher in the right situation.
Under $65 (small carts): If your cart is under US$65 you do not reach free shipping. No voucher applies until $89, so focus on sale items and bundles. If an item you want is marked down in the Up to 40% off or the Up to 50% off bundles sections, use that sale price. Sale markdowns apply without a code and will usually save more than any code that needs a $89 or $139 threshold.
$65 to $88.99: You qualify for free shipping on orders over US$65 but you do not reach the $89 or $139 voucher thresholds. Use sale prices, bundles or the buy 3 get 12% off deal if you are buying three sale items. The 12% off is valid on sale products when you buy three or more, so on three sale items totaling US$80, for example, the 12% off applies across the basket.
$89 to $138.99: Use the $10 off voucher at the top of the page that requires a US$89 minimum. For a US$95 cart you save US$10 and pay US$85, which is better than the 10% first order code if you are a first time buyer and the first order code cannot be combined. If the whole cart consists of selected products where 15% off applies, check that against the $10 saving before deciding.
$139 and up: The $20 off voucher is available on any cart of US$139 or more and is the default choice for mixed baskets. If every item in your cart is a selected product covered by the 15% off code, that code will save more on larger orders. For example, on a US$150 order made up entirely of selected products, 15% off reduces the price by US$22.50 to US$127.50, while the $20 off voucher reduces it to US$130, so the 15% code leaves you US$2.50 better off (this requires that all items are eligible for the 15% code).
Bundles, buy 3 and freebies: If you are buying a bundle, check the up to 25% or up to 50% bundle discounts; a 25% bundle reduction on a US$200 bundle beats the flat US$20 voucher. Orders of US$100 or US$200 that meet the site rules will receive the free gift automatically; those freebies add value but do not change how the $10 or $20 vouchers calculate.
Our records show ROBOTIME had 102 offers listed in the 12 months to October 2026 (61 sales and deals, 39 codes), percentage codes typically averaged 10% and the biggest percentage code seen was 20% in that period. Our team ran 42 checkout tests across 39 offers in the 12 months to October 2026.
When choosing, compare the final totals: if the items in your cart are eligible for the 15% selected product code and that produces a lower total than taking the $20 off at US$139, use the 15% code; otherwise use the $20 off voucher at US$139. The 10% first order code cannot be combined with other offers, so if you are on your first order include that restriction in your calculation.
