+
+Acquire Valued Shoppers (AVS) from the 4DBInfer benchmark: a retail dataset of customer transaction histories and promotional offers, used to predict shopper behavior such as offer repeat purchases.
+
+## Schema
+
+![schema diagram](schema.svg)
+
+Open [`schema.svg`](schema.svg) for a zoomable view: each table lists all of its columns and types, with primary keys, foreign keys, and the foreign-key edges between tables.
+
+Splits: validation `2013-07-30 00:00:00`, test `2013-07-31 00:00:00` (rows up to a split's timestamp are the inputs for that split).
+
+## Tasks
+
+| task | kind | type | description |
+|---|---|---|---|
+| `repeater` | external | binary_classification | Predict whether a shopper becomes a repeat buyer of an offer. |
+
+## Loading
+
+```python
+import relbench
+ds = relbench.load_dataset("dbinfer-avs")
+task = relbench.load_task("dbinfer-avs", "<task>")
+```
+
+Manifest layout (`manifest.yaml` + plain parquet); see the RelBench [CONTRIBUTING guide](https://github.com/snap-stanford/relbench/blob/main/CONTRIBUTING.md).
