Cross-border Shopping Pulse — observed interest in Amazon products

Three weeks of Amazon product pages that cross-border shoppers opened in five stores: the US, the UK, the UAE, India and Japan. The same product costs more almost everywhere outside the US. Prices move every day. Most strike-through "was" prices were never charged while we watched.

Finding 1 · Same product, five Amazons

The same ASIN costs a median 1.33× its US price on Amazon UK, 1.38× in Japan, 1.49× in the UAE and 2.06× in India.

Only 21% of listings are cheaper than in the US in the UK, and 24% in Japan. In the UAE and India it is about 1 in 10 (11% and 10%). Each comparison pairs a product's median price in one store with the same ASIN's median price in the US, converted to US dollars.

UK1.33× Japan1.38× UAE1.49× India2.06× 0 US price 2× 3×

Bar: median. Black line: the middle half of listings (25th to 75th percentile). Each store's comparison rests on more than 50,000 matched listings, and more than 10,000 ASINs had a price in all five stores. US prices are shown before sales tax; UK, Japanese, UAE and Indian prices include VAT or GST. Taking out the UK's standard 20% VAT would still leave the UK median above the US (about 1.11×).

Finding 2 · How often prices change

On a typical day, about 1 US listing in 9 had a different price than the day before. Over three weeks, half of the US listings we saw on 7 or more days changed price.

For the listings that moved, the median gap between the lowest and the highest US price was 18%. The UAE moved most often: on a typical day, more than a quarter of its listings showed a new price. A little over half of all daily moves were cuts.

StoreChanged vs the day beforeMedian daily moveChanged at least once (7+ days)Median low-to-high gap
US10.8%6.4%52%18%
UK14.8%3.5%57%15%
UAE27.2%2.4%74%14%
India14.7%2.4%65%9%
Japan15.8%1.0%61%10%

"Changed vs the day before": each listing's share of consecutive observed days with a different price, averaged so that every listing counts once (more than 100,000 US listings seen on two consecutive days). "7+ days": listings seen on at least 7 of the 19 days (more than 1,000 in every store). A jump to exactly 2×, 3× or 4× is usually a pack-size switch and is not counted. Leaving clothing out of the US sample changes nothing (52%, 18%).

Finding 3 · Is the strike-through real?

For about 2 in 3 US listings that show a strike-through price, we never saw that "was" price charged in three weeks. Against the highest price we did see, the median discount was 4%, not the 15% on the label.

We took listings seen on at least 7 days whose latest price showed a crossed-out list price. Most were sitting at their lowest price of the three weeks, so the deal is real against recent prices. It is a lot smaller than the label says. The UK looks the same.

UK> 1,00015%3.8%33%57%

Three weeks is short: a list price may have been charged before 30 September. "At the 3-week observed low" means within 0.5% of the lowest price we saw for that listing in the window.

Finding 4 · Who shows a "was" price

One US listing in five shows a strike-through price, at a median 17% off. In India, 77% of listings sell below their M.R.P., at a median 45% below it.

Under India's Legal Metrology (Packaged Commodities) Rules, online listings of packaged goods must show the Maximum Retail Price (M.R.P.) printed on the pack. It is the most a seller may charge, not a recent selling price. Of the Indian listings with a strike-through that we saw on 7 or more days, only 5% were ever sold at the M.R.P. while we watched. Elsewhere, crossed-out prices are rarer: 14% of UK listings, 15% in Japan and 8% in the UAE.

Finding 5 · "Only N left in stock"

A quarter of in-stock US listings (26%) carry an "Only N left in stock" warning, and more than 1 in 5 of those warnings says "Only 1 left".

The UK is slightly higher at 29%, with "Only 1 left" in a quarter of its warnings. In the US, 41% of warnings show 3 or fewer units. The median warning says 5 (UK: 4).

Finding 6 · Order caps

46% of in-stock US listings cap a single order below the usual 30 units, and 8% cap it at 3 or fewer.

The cap is often just the stock left. When a listing shows both "Only N left" and a cap, the two are equal in 88% of cases. In the UK, 51% of listings cap an order below 30 and 11% cap it at 3 or fewer.

Finding 7 · Reviews vs Best Sellers Rank

The median number of ratings falls about 30-fold, from roughly 2,200–2,300 in the top 1,000 to 69 past rank 100,000. The median star rating stays at 4.4–4.5 in every band.

Rating counts tell listings apart and stars don't. A 4.5-star listing is typical at every rank. A listing with thousands of ratings is typical only near the top.
