Data proves July is the best month to buy apparel online!

Austan Goolsbee and Peter Klenow compared overall inflation (red line) with inflation for goods that are sold online. They controlled for the fact that many goods like housing and fresh produce cannot be easily delivered by online vendors by matching the kinds of products that are sold online with similar products that are sold in stores and found that prices have tended to fall online more than in stores. The black DPI line below is their digital price index which they compared with similar goods in their offline CPI in red.

More useful for the average consumer is their finding that the best month to buy stuff online is July because prices drop the most in July with a smaller price drop in November. One possible reason online prices are lower in July than other months is that Prime Day is in July.  That is Amazon’s big sale day which rivals anything in November.

However, the authors didn’t look at every single item that is sold online, so perhaps the apparent reductions in prices in July is mostly due to the large drop in prices for apparel. Their work makes it absolutely clear that the best month to buy apparel online is July and the worst months are September and October.

Bricks and mortar apparel stores have much less price volatility and have two peaks and troughs each year rather than the one large price drop seen for online apparel. They also have data on recreational goods which go on sale in November online:
